Abstract:In order to improve the anti-ultraviolet aging performance of poly-p-phenylene benzodioxazole (PBO) fiber, 3-aminopropyltrimethoxysilane (APTMS) was used as a bridge to build a titanium dioxide (TiO2) coating on the surface of PBO fiber.The surface morphology, interfacial shear strength (IFSS) before and after modification of fiber, and the mechanical properties before and after UV irradiation were also investigated.The research results showed that after constructing a titanium dioxide coating on the surface of the PBO fiber, the shear strength of the interface between the PBO fiber and the resin was increased by 43.5%. The UV resistance of PBO fiber was greatly enhanced, and its tensile strength retention rate was increased by 25% after 200 h accelerated aging test.
