Abstract

The invention discloses an epoxy resin-based carbon fibre compound material formed by using a high polymer (HP)-resin transfer molding (RTM) process quickly, which is obtained by forming an epoxy resin composition and a carbon fibre reinforced fabric through high-pressure resin transfer molding; the resin injection pressure is 50 to 300par; and the epoxy resin composition contains an A component and a B component, wherein the A component comprises epoxy resin, a diluting agent, a defoaming agent, a coupling agent and an antioxidant, and the B component is a curing agent. According to the epoxy resin-based carbon fibre compound material formed by using the HP-RTM process quickly, the compounding of traditional RTM and a mould pressing process is realized by utilizing a novel process form of HP-RTM, the application form and the application range of carbon fibre are greatly expanded, the problems of low production efficiency and poor dimensional stability of the processes of the traditional RTM and the like are effectively solved, and the obtained epoxy resin-based carbon fibre compound material has extensive application form and application range and good dimensional stability. The compound material has low manufacturing cost, and the diversification and the complication of the structure are realized.

Description

technical field [0001] The invention relates to a carbon fiber-reinforced epoxy resin composite material, in particular to an epoxy resin-based carbon fiber composite material rapidly formed by HP-RTM technology. Background technique [0002] Carbon fiber reinforced composite materials are one of the most advanced high-performance composite materials at present. They have the characteristics of light weight, high strength, high temperature resistance, corrosion resistance, and excellent thermodynamic properties. They are widely used as structural materials and high temperature and ablation resistant materials. [0003] Epoxy resin (EP) / carbon fiber (CF) composites are an important branch of CF reinforced composites. In recent years, with the deepening of people's understanding of EP / CF composite materials, its excellent performance has been continuously highlighted, which has prompted its usage to continue to increase. Before the 1970s, EP / CF composite materials were re...
