Study on the Ultraviolet Aging of APMOC Fiber
An ultraviolet aging test of APMOC fiber is carried out with the irradiation of xenon lamp,in which the effects of ultraviolet aging on APMOC fiber were studied by single fiber tension and FTIR.The result shows that the tensile strength,the modulus of elasticity and the elongation rate of APMOC fiber would have a change,among which the tensile strength increases by 13.7% after 6 hours UV irradiation and decreases by 2.1% after 36 hours.The C-N in amide of the APMOC fiber is broken; while the hydrogen bond combination ability and crystallinity increase by FTIR.It can,therefore,be concluded that short time UV irradiation can cause two contradictory effects on APMOC fiber.
