Application of SMC isolatieplaat op autogebied:

De toepassing van SMC-isolatieplaat in de automobielsector:

Non-metallic materials used in automobiles include plastics, rubber, adhesive sealants, friction materials, fabrics, glass and other materials, involving petrochemical, light industry, textile, building materials and other related industrial sectors, so non-metallic materials are used in automobiles It reflects the comprehensive economic and technological strength of a country, and also includes the technological development and application capabilities of a large number of related industries. Glass fiber reinforced composites currently used in automobiles include: glass fiber reinforced thermoplastic (GFRTP), glass mat reinforced thermoplastic (GMT), sheet molding compound (SMC), resin transfer molding (RTM), and hand lay-up FRP products. The glass fiber reinforced plastics used in automobiles mainly include: glass fiber reinforced PP, glass fiber reinforced PA66 or PA6, and a small amount of PBT and PPO materials. Enhanced PP is mainly used to make engine cooling fan blades, timing belt upper and lower covers and other products, but some products have poor appearance quality. Due to defects such as warpage, non-functional parts are gradually replaced by inorganic fillers such as talc and PP.

Reinforced PA materials have been used in passenger cars and commercial vehicles, and are generally used to make some small functional parts, such as: lock body guards, safety wedges, embedded nuts, accelerator pedals, shift upper and lower guards A protective cover, opening handle, etc., if the quality of the material selected by the parts manufacturer is unstable, the production process is improperly used or the material is not dried well, the weak part of the product will break. Plastic intake manifold is a new technology developed in recent years. Compared with aluminum alloy cast intake manifold, it has the advantages of light weight, smooth inner surface, shock absorption and heat insulation, etc., so it is widely used in foreign automobiles. The materials used in it are all glass fiber reinforced PA66 or PA6, mainly using the fusion core method or vibration friction welding method. At present, relevant domestic units have carried out research in this area and achieved phased results.
