Polyacrylonitrile fiber is a product used in cement and asphalt concrete materials.
As a secondary reinforcing material for concrete, and as an industrial fiber product for reinforcing asphalt concrete. It can not only greatly improve the adhesion, high temperature stability and fatigue durability of asphalt pavement, but also has the performance of low temperature crack prevention and reflection crack prevention. Effectively improve tensile, shear, compressive and impact strength. Its great role and application prospects in concrete have been increasingly recognized and accepted by the engineering community.
