Trucks’ demand for FRP composite materials

Reducing fuel consumption and reducing environmental pollution have become key issues that urgently need to be resolved in the development of the automobile industry and the sustainable development of society. The use of high-performance and light-weight materials is an important way to realize the lightweight of automobiles, which can effectively reduce the weight of automobiles and improve engine efficiency. In recent years, the United States, Europe, Japan and other developed countries have adopted the application of FRP composite materials in the automotive field, and continuously promoted the accelerated development of automotive composite materials and their products in the direction of specialization, standardization, high-quality, and environmental protection. A new world of materials.

In medium and heavy trucks, the application of FRP composite materials is particularly active, involving front wall masks, bumpers, fenders, wheel covers, side panels, footboards, air deflectors, air deflectors, side skirts and engines Internal parts and other parts. In FAW Jiefang’s improved model 142, the engine case oil cover and oil filter cover are molded by SMC, and the chassis floor is pultruded; FAW Jiefang heavy truck front and rear bumpers, front wall panels, air deflector, and cab top cover are used SMC compression molding, RTM or hand lay-up process molding. The front wall and wheel covers of Dongfeng trucks are produced by SMC. Although this model has been improved many times, the above components have been used continuously for many years. Dongfeng trucks also use SMC components such as water tank masks, windshields, air intake pipes, and air deflectors. Beiqi Foton Auman heavy truck front flip cover, left and right fenders, deflector, deflector, side skirts, pedals, bumpers, etc. are all made of glass fiber reinforced plastic composite materials, mainly using SMC molding process, and some parts adopt Hand lay-up and RTM process. The face shield, sub-bumper, and foot pedal of Steyr heavy truck are molded by SMC, the sunshade is made of transparent glass fiber reinforced plastic hand lay-up technology, and the deflector is hand-laid FRP technology. The front panel, left and right corner plates, and left and right spoilers of Volvo heavy trucks produced by Jinan Heavy Truck Huawo are all produced with SMC or RTM. The face shield, wind deflector and front wall lower protective surface of the improved Yellow River heavy-duty truck are all made of SMC or hand-laid FRP materials. In light trucks, the application of FRP composite materials is also expanding.

Development and application of new technologies and processes. With the strong demand for lightweight automobiles and the need to reduce overall production costs, the development and improvement of new glass fiber reinforced plastic technology will be promoted. With the continuous emergence of new models and the increase and improvement in the demand for FRP composite materials, new issues and new risks will inevitably arise. These are the arduous tasks facing domestic manufacturers of relevant automotive FRP composite materials.
