Abstract

The invention discloses a high glass fiber content enhanced high-temperature nylon composite material and a preparation method thereof. The high glass fiber content enhanced high-temperature nylon composite material is composed of five components by weight: 30-90 parts of high temperature nylon resin, 20-60 parts of chopped glass fiber, 1-10 parts of a flexibilizer, 0.1-1 part of an anti-oxidant and 0.2-2 parts of a lubricant, Compared with the commonly used glass fiber reinforcement high-temperature nylon composite material on market, the tensile strength, the tensile modulus, and the impactintensity of the high glass fiber content enhanced high-temperature nylon composite material are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-temperature nylon composite material reinforced with high glass fiber content and a preparation method thereof. Background technique [0002] Nylon has good comprehensive performance. At present, glass fiber reinforced nylon composite material is a high-performance reinforcement material widely used at home and abroad. High-temperature nylon is concerned by various industries at home and abroad because of its high melting point and its ability to work continuously at high temperatures. Glass fiber has many excellent properties such as high mechanical strength, good heat resistance, excellent corrosion resistance, and good insulation. It is widely used in electronic equipment, building materials, sports equipment, aircraft and automobiles and other fields. However, glass fiber reinforced nylon materials currently on the market are mostly reinforced PA...
