Polyacrylonitrile fiber for concrete reinforcement PAN fiber

Polyacrylonitrile  fiber, known as PAN fiber, was a kind of synthetic fiber which made by acylonitrile copolymer. Recently, experimental tests have shown PAN fiber to have an average strength of 40 cN/dtex. Their high stiffness, tensile strength, chemical resistance, and electrical and thermal conductivity make them attractive for applying as reinforcement for specimens, including concrete materials. In the lastest decade, as a kind of green material for concrete, PAN fiber is considered as a promising candidate in a wide range of applications . studied the performance of fiber reinforced asphalt concrete (AC) under environmental temperature and water effects and he found that the fibers have significantly improved AC's rutting resistance, fatigue life, and toughness. The flexural strength and ultimate flexural strain, and the split indirect tensile strength (SITS) at low temperature have also improved.
