紫外光辐照对PBO纤维复合材料力学性能的影响
Effect of UV-visible light radiation on mechanical properties of PBO fiber reinforced composites
摘要
Abstract
The effects of UV-visible light radiation on PBO fiber reinforced composites were studied in this paper by using a UV-visible light weatherometer,a universal testing machine and dynamic mechanical analysis(DMA).The results indicate that the tensile strength,flexural strength and interlaminar shear strength of PBO fiber reinforced composites decline to some extent after UV-visible light radiation,while the tensile and flexural modulus of the composites experience little changes.The heat-resistance property and rigidity of the composites increase to some extent after UV-visible light radiation.However,the E′and E″of the composites shift toward low temperature with exposure time increasing,which means some decline of heat-resistance property and rigidity of the com-posites.关键词
