The influence of the short-term ultraviolet radiation on the structure and properties of poly(p-phenylene terephthalaramide) fibers

▸ The effect of the short-term UV radiation on properties of PPTA fibers was studied. ▸ The properties include surface properties, mechanical and thermal resistance. ▸ Surfaces of radiated fibers are rougher and have more oxygen-based functional groups. ▸ Radiation does not change the chemistry and crystalline structure of fiber core. ▸ The structure-property relation of PPTA fibers during the UV radiation was build.
