How composites changed the automotive industry

Car manufacturers today are building cars in whole new ways than in the past, using new materials and new technology. One of those materials is composites. Let us take a look at how composites changed the automotive industry. 


Lightweight, durability and corrosion resistance

Thanks to composites, cars today weigh less than ever before, providing great power to weight ratios while also making cars safer. Carbon fibre and fibreglass composites are incredibly strong and durable materials and have been used in the automotive industry for race cars and supercars for decades. 


Reducing the weight of the car has many benefits outside a car’s performance. A lighter car means the suspension has less weight to carry making it easier to adjust as the car hits bumps in the road. The braking system also sees relief from reducing the weight because the heavier an object is, the harder it is to stop. In conclusion, using composites when building cars make the suspensions and braking systems more effective and last longer.


Lastly, unlike steel and some aluminium alloys, composite materials do not rust. This is incredibly beneficial to a majority of cars that experience corrosion due to ice, snow and salt exposure, which in many countries happens to be a lot of cars. The corrosion resistance composites provide means that cars last longer and are more durable


Endless possibilities for customisation 

Composites are easy to customise and mold into different shapes. They require different tools to work on than metal and do not require specialist trades such as welding and metal-bending. Composites can be used to create an infinite number of shapes without losing their structural rigidity. They can be molded, bent and shaped in so many ways the possibilities are essentially endless


With the rise of composites use in the automotive industry, composites have become cheaper and the more popular choice than ever before. While some have been used exclusively for the sports car and supercar markets in the past, today composites are becoming a part of life for many consumer cars.
