Long fiber modified mateirals for lightweight auto parts new energy sector
The automotive industry has become the fastest growing area of the demand for modified plastics, which is driven by the lightweight of automobiles.The largest downstream application fields of modified plastics are home appliances and automobiles. Drived by the lightweight of automobiles, the automobile industry has become the fastest growing area of the demand for modified plastics. It is expected that in the next few years, the average annual growth rate of the demand for modified plastics for automobiles will be more than 15%. Modified plastics are better than general plastics in flame retardancy, strength, impact resistance, toughness and other aspects. They are mainly used in household appliances, automobiles, construction, office equipment, machinery and other fields, among which household appliances and automobiles are the two largest application fields. Interior weight loss can be reach by using modified plastics, reduce the weight of the body and chassis in addition to the use of high strength steel, aluminum and magnesium alloys, some researchers have even proposed the concept of all plastic body, puts forward the concept of integrated ultra-light new energy vehicles, super light new energy automobile main cells by the driver, driving system, steering system, aluminum alloy frame, and other components of the composite material body, plastic floor, body can curb weight down to 850 kg of modified plastics application in automobile interiors. The dashboard At present, there are two forms of instrument panel, hard instrument panel and soft instrument panel. Soft instrument panel is generally used by high-grade cars, while buses, trucks and other models are basically hard instrument panel.The instrument board is generally made of modified PP material. The modified PP is mainly made of rubber toughening agent and inorganic filling material.Dashboard skin material is mainly PVC/ABS, PVC is weak in impact resistance and heat resistance, ABS mechanical properties and forming processing ability is better, and can be combined with PVC, the combination of the two can form complementary. Door panel At present more commonly used manufacturing door plate modified plastic is ABS, PP, with them made into a skeleton, and the surface with a layer of buffer layer.In some models of GM and Chevrolet, glass fiber reinforced unsaturated polyester sheet molding plastic is used to modify the application of plastic in functional parts and structural parts Bumper Car bumper is one of the main parts of the use of modified materials, most of the bumper on the market are made of plastic products, the bumper panel is PP, PC/ABS, PC/PBT and other materials, the skeleton is wood or metal materials, the middle part is PP foaming materials.This kind of material is not conducive to recycling from the perspective of environmental protection. After continuous innovation, TPO can be used in the production of bumper panel, glass fiber reinforced PP material can be used in the s...
