Automobile is the pioneer among globalized industries in the modern society. Future automobiles are asked to be lightweight and fuel-saving, while keeping safe and durable. For the breakthrough to meet the challenging demand, more and more vehicles want new materials, where composite stands out.

Another advantage of composite is that it meets the strict rules concerning environment protection. With the development of raw materials and technologies, composites will certainly be dominant in vehicle construction.

Advantages of composites on vehicles

Reduced weight:

The density of most resin composites is within 2g/cm3. The reduction of car weight improves fuel efficiency. Statistics show that every 100kg weight reduction saves 0.7L fuel per 110km.

Flexible design:

The curing of composites is after the shaping. The shaping of curve components is usually hard for metals due to the thickness. But when it comes to composite, the problem will resolve. It is also more reasonable in both aerodynamics and aesthetics.

Short developing time:

The preparing of the composite material and the forming of its final product are almost simultaneous. Reasonable design fits the composites into an integrated forming process. Although the components differ in various thickness and shapes, they can be formed together at the same time. For metal parts, this is almost impossible, not to say the efficiency and accuracy. Take the Boolean bart for example, to complete its front panel if using steel, it needs more than 20 components. What if composite panels? Only 7! It is reported that, for 20000/a out put, the preparing time of metal is 15 months, but composites only 6 months! According to Ford research, a composite car consumes 20% less components than a metal one, and costs 60% less in processing, and 25% to 40% less in part connecting (metal parts have to connect by welding).

Impact resistance:

Due to the inherent structural of the composite itself, it has a large coefficient of vibration attenuation. In case of a crush, the composite can absorb a large amount of energy and keep the passengers safe.

Corrosion and chemical resistance:

Many parts on vehicles are demanded to be resistant to petroleum and diesel, gasoline and engine oil, transmission fluid and other types of oils. It’s even necessary for some to withstand extreme weather like hot, cold and salt atmosphere. In contrast with metals, composites are much easier to survive in such conditions and keep high performance.

Small input and easy update:

The modern vehicle industry is updating rapidly. It’s hard for metal factories to keep up with the pace due to its fixed amount of equipment and models. The quick processing and model-shifting of composites, on the contrary, enable a small input to meet the changing market.
