Polyacrylonitrile fiber, also known as acrylic fiber, has higher elastic modulus, tensile strength, UV resistance, high temperature and cold resistance than polypropylene fiber. As the main reinforcement of cement concrete and asphalt concrete, it can significantly improve the tensile strength, fatigue strength and flexural tensile strength of concrete, and significantly improve the early crack resistance of concrete. It is used in asphalt to significantly improve the adhesion, high-temperature stability and fatigue durability of asphalt, and has low-temperature crack prevention and reflection crack prevention, and effectively improve the tensile, shear, compressive and impact strength. The real function and application prospect of polyacrylonitrile fiber in concrete have been recognized and accepted by the engineering community.
