Abstract

The invention belongs to the field of high-temperature resistant nylon composite materials and relates to a basalt fiber reinforced semi aromatic nylon composite material. The material is prepared from the following components in parts by weight: 100 parts of semi aromatic nylon, 15-45 pats of basalt fibers, 5-15 parts of flexibilizer, 0.2-1 part of coupling agent, 0.3-0.8 part of thermal stabilizer, 0.5-1.5 parts of lubricant and 0.3-0.8 part of crystallization nucleating agent. Compared with an alkali-free E glass fiber reinforced high-temperature resistant nylon composite material, the basalt fiber reinforced semi aromatic nylon composite material provided by the invention has higher strength, better heat resistance and lower water absorption. The material provided by the invention is simple in preparation process, high in production efficiency and suitable for large-scale popularization and application, and has very good social and economic benefits.
