摘要：
A jute fiber/polyester fiber composite material was prepared by using sheath- core structural polyester fiber as binder. The jute fiber/polyester fiber composite material was treated with a phosphorus- based compound to achieve flame retardant. The flame retardant jute fiber/polyester fiber composite material was accelerated aging by ultraviolet, and its mechanical properties and microscopic morphologies of the composite during the aging process were observed. Results show that the tensile strength and tensile modulus of the composite gradually increase in the first 10 d with ultraviolet irradiation, and then gradually decrease. The initial tensile strength and tensile modulus of the flame retardant jute fiber/polyester fiber composite are higher than those of the original jute fiber/polyester fiber composite. After 10 d of UV irradiation, the mechanical properties of the flame retardant jute fiber/polyester fiber composite decrease faster than the original jute fiber/polyester fiber composite. Microscopic morphologies results show that the jute fiber structure gradually becomes loose and produces transverse cracks during the aging process. Moreover, a large number of transverse cracks appear in the polyester fibers. The flame retardant treatment accelerates the aging of the jute fiber/polyester fiber composite. © 2022, Editorial Board of Polymer Materials Science & Engineering. All right reserved.
