It's estimated that reducing the weight of a car by 10% can save 6% to 8% in fuel. As a significant lightweight material replacing steel in car construction, fiberglass/composites are inextricably linked to car fuel efficiency, environmental protection, and safety. Manufacturing car body shells and other related parts with fiberglass/composites is one effective way to achieve car lightweighting. The introduction of fiberglass/composites has provided significant conditions for car design innovation, offering greater design freedom and ease of shaping, adding novelty and aesthetics to the design and functionality of car products, and realizing the design concept of streamlined car bodies. Additionally, fiberglass/composites offer excellent properties such as safety, low noise, and thermal insulation.
Due to the weight reduction of vehicles, rolling resistance is reduced, leading to a series of benefits such as lower fuel consumption, energy conservation, reduced environmental pollution, and enhanced safety. The application of glass fiber reinforced plastics/composites in the automotive industry began in the 1950s in developed countries like the United States, Europe, and Japan; now, they are widely used in the manufacturing of car bodies and related components for passenger cars, coaches, trucks, tractors, motorcycles, racing cars, refrigerated vehicles, and engineering vehicles.
