Research progress in surface treatment of polyacrylonitrile-based high-strength and high-modulus carbon fibers
High-strength and high-modulus carbon fibers are high-performance carbon fibers that can simultaneously balance strength and modulus.However,their high modulus leads to an increase in surface inertness and a decrease in interfacial shear strength of composite materials.Surface treatment can effectively enhance the wettability and surface chemical activity of high-strength and high-modulus carbon fibers.The preparation process of high-strength and high-modulus carbon fibers and the evolution of their interfacial properties are briefly introduced.The research progress in surface treatment of high-strength and high-modulus carbon fibers is systematically discussed,and the development trends and application prospects of surface treatment for high-strength and high-modulus carbon fibers is prospected.
