In short by combining specific materials and adjusting them, composite materials can be tailored to any vehicle. As mentioned by BBC's Bitesize, "The materials for a composite material are chosen because they have different properties that combine to make a more useful material. Steel-reinforced concrete is a composite material. It is made by pouring concrete around a mesh of steel cables.
Also known as Fiber-Reinforced Polymer composites are made from a polymer matrix that is reinforced with an engineered, human-made or natural fiber. Think of carbon fiber, concrete, or even aramid fiber. Say you want to build the ultimate sports car; something that is sleek, strong, fuel efficient and obviously fast.
You would use composites to ensure your vehicle is safe, but also light and fuel efficient. However, the benefits of using composites in the automotive industry do not end there.
Here is everything you need to know about using composites in the automotive industry. The weight of a vehicle affects not only the performance of a car but also impacts its, fuel efficiency. Composites are light weight compare to other more common materials , like wood and metals.
Lightweight cars can take on bad roads, safer, and can be stronger, all thanks to composites. Composite materials tend to protect your vehicle from any short term corrosion. Composites tend to be very resistant to the harsh chemicals that can eat away at your car over time. Because of their unique properties and freedom for manipulation, composites can resist even some of the harshest external elements.
The s was an incredibly important time for the advancement of composites. Glass fibre was introduced by Owens Corning who also started the first fibre reinforced polymer FRP industry. The resins engineered during this era are still used to this day and, in , unsaturated polyester resins were patented. Two years later, higher performance resin systems became accessible.
The first carbon fibre was patented in and then became commercially available. Then, in the mids , composites were starting to become increasingly common for manufacturing processes and construction due to their relatively cheap cost compared to materials that had been used previously. The composites on a Boeing Dreamliner in the mids substantiated their use for high strength applications.
Weight saving is one of the main reasons for using composite materials rather than conventional materials for components.
While composites are lighter they can also be stronger than other materials, for example, reinforced carbon-fibre can be up to five times stronger than grade steel and only one fifth of the weight, making it perfect for structural purposes.
Another advantage of using a composite over a conventional type of material is the thermal and chemical resistance as well as the electrical insulation properties.
Unlike conventional materials, composites can have multiple properties not often found in a single material. Fibre reinforced composites, such as fibre reinforced plastic FRP composites , are finding increasing use in the design and manufacture of final products for commercialisation. TWI has been carrying out research and development into composite materials for over 25 years. Our expertise covers all aspects of working with composites including design, modelling, processing, repair, NDT, failure analysis, joining, added functionality coatings and testing.
Find out more on how we can help using composites. The growing uptake of composites has been driven by the need to make light, strong, corrosion and fatigue-resistant structures. Composites are manufactured using one of the following techniques; wet lay-up, spray-up, compression moulding, injection moulding, resin transfer moulding, vacuum infusion, filament winding, pultrusion and prepreg.

The primary reason composite materials are chosen for components is because of weight saving for its relative stiffness and strength.
For example, carbon-fibre reinforced composite can be five times stronger than grade steel while having only one fifth of the weight. Aluminium grade is much nearer in weight to carbon-fibre composite, though still somewhat heavier, but the composite can have twice the modulus and up to seven times the strength. The composites industry is an exciting industry to work in because new materials, processes and applications are being developed all the time — like using hybrid virgin and recycled fibres, faster and more automated manufacturing.
As with all engineering materials, composites have particular strengths and weaknesses, which should be considered at the specifying stage.
Composites are by no means the right material for every job. However, a major driving force behind the development of composites has been that the combination of the reinforcement and the matrix can be changed to meet the required final properties of a component.
For example, if the final component needs to be fire-resistant, a fire-retardant matrix can be used in the development stage so that it has this property. Skip to main content. Menu Toggle navigation. Supporting UK Composites. Search form.
