Carbon Fibre’s use in Cars
It may come as no surprise to you that the amazingly strong and lightweight material – carbon fibre – has been used in some of the high-end sports cars and racing cars. Cars like the Koenigsegg Agera, the McLaren Senna, Porsche’s 918 Spyder, the Ferrari LaFerrari, Alfa Romeo’s 4C, and BMW’s i8 use a carbon-fibre monocoque body shell in their design. Even BMW’s recent i3 EV city car boasts a carbon-fibre monocoque cell.
Of course, there are many pieces that make up a car’s whole, many of which there are components which can also be made up of carbon fibre, and these are actually more prevalent in different forms and measures throughout the motoring industry, particularly in high-end luxury cars. In some of BMW’s and Porsche’s latest premium cars, carbon fibre has been introduced in various arrangements within the vehicles’ body components. Obviously, the rarer the part, then it will have quite an expensive price tag attached.
Then there are multiple smaller workshops and larger businesses dedicated to creating special automobile parts and designs made from the composite material carbon fibre. Some of these components might be a certain air diffuser or spoiler to make the car look more aggressive or more aerodynamic. Some of these businesses even make carbon fibre interior wraps with a distinctive pattern to make an individual’s car stand out from the crowd.
So, what is carbon fibre?
A quick science lesson first to help us understand: Carbon is number six on the periodic table, and so the carbon atom consists of 6 protons, 6 neutrons, and 6 electrons. Two of the 6 electrons fill up an electron shell close to the carbon atom’s nucleus, while the other four electrons sit in a half empty electron shell around the outside. These electrons running about on the outside shell are known as valence electrons and are the key to carbon’s amazing and incredible properties. Any electrons in an atom’s outer shell are involved in taking part in forming chemical bonds. How many bonds these electrons are involved with depend on how much room there is in the outside shell. What makes carbon so amazing is that it has got space for four other electrons to make its outer shell full. This attribute makes carbon a four-way connector that can link atoms together.
A polymer is any material that is made of long, repeating chains of molecules. So, carbon can build up straight chains of carbon atoms, carbon chains with branches, and even carbon chains that are joined end to end to make loops! So, a carbon polymer is made up of chains and chains of carbon molecules that are linked up in a scaffolding-type structure. Carbon can bond to itself, but, when it doesn’t, the end of the carbon chains can terminate with other elemental atoms. For example, a carbon chain can finish up with a small hydrogen atom, which makes these chains slippery like in oils. Carbon chains can also connect to other groups of elements, making them a specific ‘functional group’, each group having a different chemical property.
Graphite is a crystalline form of the carbon element. Individual layers of graphite are some of the strongest structures that we know about in the universe. Carbon fibre material is made up of individual layers of graphite, which on their own are quite slippery. Carbon-fibre-reinforced polymer (CFRP) composites (also known as carbon-fibre laminates) are made up of woven layers of nearly pure carbon fibres that are bonded together by a hardened plastic like an epoxy resin. CFRP composites are therefore extremely strong and stiff.
A stretched carbon fibre is up to five times the strength of steel, as durable as steel, but only a quarter of steel’s density. Being this strong and much less dense than steel makes carbon fibre a lighter and stronger material than steel. On top of being extremely strong and lightweight, carbon fibre is also high in chemical resistance, has a high stiffness, has low thermal expansion, has a low weight to strength ratio, and is tolerant of excessive heat. These are the reasons why carbon fibre is so sought after in the motor racing arena and in high-grade luxury sports vehicles? These amazing properties make carbon fibre a very popular material for use in aerospace, military, recreational, as well as in automotive industry applications.
As CFRPs become more readily available, the trickle down effect will see it being more and more a part of a new mainstream motor vehicle, EVs included.
Travelling with a Roof-Top Tent
Got your trusty Outback or Forester, maybe a Patrol or even a new Cherokee? Then you’re likely ready for a bit of an adventure! Haven’t we got the country just for you? Australia is filled with many wonderful things to see, places to explore, and amazing wildlife and flora to enjoy. It’s surprising how many decent vehicles we can actually use to get around Australia; space and practicality being the main factors contributing to the type of vehicle we end up using.
Of course, the other factor will be how 4x4ish and AWDish you’ll want/need the vehicle to be – because the further you go off-road, then the more likely you’ll be driving an SUV with 4WD ability or even a true blue 4×4 brute to get you anywhere.
Next question I’d be asking would be: Will you want to be staying in motels and B&Bs, towing a caravan, or staying in a tent? If you want to ditch the vacancy/no-vacancy signs for a lot more freedom and a lower price tag, then caravanning and tenting are very decent options.
What I wanted to focus attention on was the types of tents that can be mounted on the roof of a vehicle. Roof-top tents are a means of accommodation that are great while you’re on the move around Australia. They keep you up off the ground and away from the creepy crawlies, or at least minimalizing their access! A pop-top roof tent is a neat and inexpensive way of giving you your sleeping space while travelling around Australia.
Some of the advantages of having a roof top tent include:
You can camp in as many places as your vehicle can take you – think off-road and a rugged 4×4 vehicle!
The roof-top tent is usually designed to be fast and easy set up and store away at a campsite. Usually, they can take as little as 1 – 5 minutes to set up. This is a brief!
The roof-top tent is off the ground, thus keeping you off the wet ground and mud, and away from insects, snakes, and other animals.
Many pop out roof-tents are designed with the mattress already included in the fold out design. This makes camping life even easier.
The biggest disadvantages of a fold out roof tent would include:
Older folk may struggle getting in and out of the tent via the ladder.
The tent’s maximum body capacity and height are limited, so there’s no way for you to stand up to your full height. You also won’t be able to hold a party of any great number inside.
Lifting the tent to the roof of the car can be a little more challenging depending on the set-up and weight involved.
Unfortunately, not every vehicle is made for carrying a hefty weight on the roof, and some simply cannot handle the additional weight. As a general rule of thumb, your car should have cargo racks and be able to withstand at least 80–100 kg of weight. They should accommodate for the weight of your tent and everyone inside. However, if you’re thinking of buying a four-person roof top tent, you’ll need a sturdier SUV or a pickup truck/ute. Some sedans and town cars may be able to handle one- or two-person pop-top roof tents.
Roof-top tents have been an Australia thing for many, many decades, but the first one was invented between 1957 and 1958 by Giuseppe Dionisio. Roof top tents are now available right around the world, and the variety of roof-top tent models is staggering.
For your first ever roof top tent experience, a softshell tent might be the best choice. It is lighter, cheaper, and more familiar to most people for setting up at a campsite. However, if you’re ready to go all in and have the money to spare, a hard shell roof top tent is a more luxurious (and usually more convenient) option.
Thule and Kings roof-top tents would be a great place to start if you want to take a look and try out the camping lifestyle with a view. Camping life with a bit of freedom is hard to beat!
Young Drivers
Safety Tips for Young Drivers.
- Get supervised driving experience in all types of weather conditions and road surfaces (clear weather, dawn/dusk, rain, high winds, dust, gravel, hill climbs, descents, etc.).
- Get someone who is an experienced driver to supervise you lots while driving town/city rush hour traffic, around roundabouts, out on the motorway, changing lanes, urban and rural driving. etc. Don’t just practise in an urban area, make sure you get experience driving on all types of roads with a confident driver alongside to guide you as and when you may need it.
- Be courteous when driving and think of other road users.
- Look as far ahead as possible, and not just at the taillights of the car in front of you, which is how nose-to-tail accidents happen.
- Put your phone away when you’re driving, or at least where you can’t see or reach for it. Driver distraction is a leading cause of crashes.
- Don’t let passengers push you beyond your comfort zone. It’s your responsibility as the driver to stay alert, ensure how safe is safe for you, the safety of yourself, the safety of passengers, and the safety of others while driving.
- When choosing a car, look for solid cars with technology like ABS, airbags, and pre-tensioning seatbelts.
- Get a car with great visibility about the car.
- Parents, family members, and those with driving experience should supervise you (the young driver/learner) as much as possible.
As a parent or guardian, let your young learners drive, even if it’s just for short distances each time. It is so important to help them get experience behind the wheel while being supervised as much as is possible and practical.
In 2008, OECD data revealed that the United Kingdom (UK) had the lowest fatalities per billion vehicle kilometres travelled when compared with other countries who were OECD members. In this survey, the graphed data showed Australia as being 9th out of the 13 countries involved in the survey. Where the UK had 4.9 fatalities per billion vehicle kilometres travelled, Australia had 6.9. Denmark held the highest with 8.22.
Recently, Top Tests, UK, revealed data on various driving statistics. Top Test’s 2018 data showed that drivers aged 16–19 were still 38% more likely to be killed or seriously injured than drivers aged 40–49, and drivers aged 20–29 were 65% more likely to be killed or seriously injured than drivers aged 40–49. When 1000 drivers were quizzed in 2018, Top Tests found that 42% of the drivers aged 18–34 admitted to experiencing road rage at least once a week, and 14% of younger drivers experienced road rage every day that they drove.

Across the ditch in NZ, AMI insurance claims data reveal that drivers under the age of 25-years old are most at risk of having an accident. In the United State, motor vehicle crashes are the second leading cause of death for U.S. teens. Here in Australia, the government has kept a close eye on road statistics as well, and rightly so. According to 2021 reports, there were a total of 1133 road fatalities for the 2021 year, where speeding remained the top cause of accidents; this was followed by driver distraction, and then driver fatigue. Those aged 17 – 25 year old were the second-highest age bracket impacted by road deaths. The 40 – 64 age group had the most road accident deaths, however it was young men who were more likely to be involved in a crash.
By March this year (2022), New South Wales had recorded the most fatal road accidents for the year (25), an increase from 2021 with (19). Queensland followed (20), Victoria (18), Western Australia (15), South Australia (7), Tasmania (6), Northern Territory (3), and the Australian Capital Territory (0)
Whether it’s travelling too fast for the conditions, using smartphones, vaping or smoking, eating, applying makeup, checking the texts – all while driving – these are the leading causes for road fatalities on Australian roads. Driving while fatigued and, of course, drink driving or driving under the influence of some drug also causes road fatalities.
It’s sad that anyone should die, however it is the young drivers that are the top culprits for using their mobile phones while they are driving, which leads to serious and tragic accidents. In Australia, 18 – 24 and 25 – 39 age groups reported the highest application of using mobile phones while driving. 18 – 24 year old drivers are twice as likely to receive a speeding fine.
Hamish Piercy, Fleet Risk Manager for AMI, and former New Zealand Police Officer with the serious crash unit, has over 33 years of crash investigation experience. Hamish was unsurprised that, in New Zealand, AMI received such a high number of claims for drivers under the age of 25. He commented: “There are a lot of great young drivers out there, and some excellent driver education programmes, but these statistics show that we can’t be complacent when it comes to driver safety. It’s an unavoidable fact that to gain experience, you have to drive. So, as a society we need to look at how we can enable that in safe ways.”
If possible, try to enrol your young family member that’s embarking on getting a driver’s license to run through a local driver training course. Good driving courses will focus on key areas like core driving skills, reading the road ahead, distraction, inattention, and speed. Courses that can impart crucial driving skills will enable your youngster to gain confidence, gain good driving skills and driving habits, and get plenty of positive encouragement. These are all essential for getting out on the road to drive as safely as possible.
Safe driving everyone!
Destination Freedom and Vehicles for the Physically Challenged
There are many wonderful people with some sort of physical disability that they’ve had since birth or from an incident later in life which caused the disability to come about. All are inspirational people.
Being allowed to drive when you are physically challenged offers you so much more independence and heaps more confidence. Driving offers a sense of freedom to do what you want whenever you can, so it gives you more opportunity to find a job and get to work, volunteer for others, and go to the other side of the continent solo, or with family and friends, when you want to just as you see fit.
Being physically challenged is on its own a significant hurdle to overcome on all fronts when it comes to being able to do life like a person with a fully functional body. There are many difficulties for a physically challenged person to deal with, and one of those is simply getting from Place A to Place B on time.
If you were/are a person with a physical disability who wants to be able to drive to your own Destination Freedom, then finding and owning the right vehicle that’s just right for you will be the first box to tick. Sometimes the vehicle may need to be modified to suit your own unique requirements. My Uncle Frank, a 2nd World War veteran who has since passed on, suffered a war injury from flying shrapnel. This brief fateful moment caused Uncle Frank to become paralysed in his left arm as well as partially in his left leg. He was still able to walk with a shuffle, drive a car (an always-shiny brown Toyota Corona) with an automatic gearbox, and give everyone a good laugh with his great sense of humour. A small bracket with a fixed swivelling knob was attached to the steering wheel of the car so that he could turn the car with ease, using his good hand and arm to steer.
Many other people have had accidents that even left them a paraplegic and confined to a wheelchair for mobility. Any accident can be life changing, none more so than a spinal cord injury. Yet still it is possible for these people to drive. A former New Zealand equestrian champion, Catriona Williams, who is now a tetraplegic after falling from her horse in 2002, still enjoys an independent life filled with fun. Enjoying adventurous road trips with family and friends is made possible with her modified Volkswagen Caravelle van, which has been set up for her to be able to drive securely from her wheelchair.
There are clever people who have the engineering skills enabling them to modify a vehicle for many people with physical challenges.
Some of the special equipment you can use to modify a vehicle include:
- Infrared remote control systems that enable easy access and operation of a vehicle from a wheelchair.
- Controllers for wheelchair movement (i.e. ‘Slip and Puff’ systems via sucking and blowing through a straw-like device.).
- Headrest indicators the indicators are activated by head movement on the head rest.
- Mini steering wheels that enable people with limited upper body strength to steer the car with ease.
- Joystick or foot steering, which can be combined for steering, acceleration, and braking.
- An array of hoists and roof racks for various reasons.
- Seatbelt modifications, harnesses, and special seating.
- A left foot accelerator pedal instead of a right foot one.
- Various hand controls that can of themselves incorporate up to seven unique functions – i.e., steering, high beam lights, horn, wipers, indicators etc.
These are just some of the possibilities. Pretty much any car can be modified, new or old. MPVs and vans are ideal for a person who is looking to drive the vehicle from their wheelchair. It’s awesome there are great opportunities out there for enhancing quality of life.
