Basalt fiber is inorganic fiber with high performance, between carbon fiber and glass fiber, but the price is only 1/5-1/2 of carbon fiber (T300 level).Basalt fiber has many unique advantages, such as outstanding mechanical properties, high temperature resistance, acid and alkali resistance, low moisture absorption, good insulation, excellent insulation and sound insulation performance.At present, it is mainly used in the field of transportation infrastructure and building materials, but with the continuous development of technology, the scope of application is gradually expanding.

At present, the global low-carbon economy is gradually deepening. In order to meet the needs of environmental protection and energy saving, vehicle lightweight has become the trend of automobile industry development, among which lightweight materials are the key link.Basalt fiber reinforced resin matrix composites as a new type of structural materials, with low density, low thermal conductivity, low moisture absorption rate and stable chemical properties, used in automobiles, can significantly reduce the structure weight, reduce fuel consumption, reduce exhaust pollution, both can satisfy the requirement of high performance processing for automotive materials development, also accord with a country to the requirement of automobile materials of green environmental protection, has a good application prospects in the automotive industry.
