Abstract

Abstract: Epoxy is a widely used matrix material in aerospace field because of its good bonding ability, dielectric properties and good processing performance. However, the poor fracture toughness of curing epoxy resin caused by the high cross-linking density greatly limits its application in aerospace advanced composites. In this paper, the recent development of epoxy resin toughened by hyperbranched polymers, thermotropic liquid crystal polymer, interpenetrating polymer networks and nanoparticles is reviewed, and the application in aerospace field was introduced and prospected.

Key words: toughen, epoxy resin, modification, composites, research progress
