The impact of UV radiation on the high-temperature behavior of polyphenylene sulfide (PPS) fiber was investigated in this study. The ultimate strength. failure strain elasticity modulus and toughness were employed to evaluate the degradation caused by the coupling effects of UV radiation and high temperature. The degradation characteristics of PPS fiber were observed and evaluated bas... https://parisnaturalfoodes.shop/product-category/omega-3-d-high-epa/
