The work aims to solve the problems of high cost, environmental and health hazards, and poor chemical resistance of epoxy resin synthesized from bisphenol A in carbon fiber reinforced epoxy resin composite materials and replace bisphenol A with lignin in synthesizing epoxy resin to prepare carbon fiber composite materials. Through the review on the research progress of the modification methods and schemes of lignin in the synthesis of epoxy resin, the advantages and disadvantages of the carbon fiber composite molding process are analyzed. Different methods are used to chemically modify lignin, which can reduce the cost while improving various properties such as thermal stability and chemical resistance. Using modified or degraded lignin to synthesize the epoxy resin matrix of carbon fiber composite materials provides a new research direction for the research of carbon fiber reinforced materials, which has a positive effect on reducing costs, improving performance and promoting industry development of carbon fiber reinforced materials.
