摘要
Abstract
In our current study,flax fiber was modified by three silane coupling agents(KH550,KH570,A171),and the modified flax fiber was combined with polypropylene(PP)to make modified flax fiber/PP composite material.The results showed that the maximum decomposition temperature of flax fiber before and after modification ranged from 353.42℃to 363.35℃,and the addition of silane coupling agent had no significant effect on the thermal stability of flax fiber.The tensile strength results showed that silane coupling agent improved the interfacial compatibility between flax fiber and polypropyl-ene,and the tensile strength of the composite made of flax fiber treated with KH570 was the best,reaching 35.54 MPa.Com-pared with the composite prepared by the KH550 and A171 modified flax fiber,the KH570 modified flax fi-ber/polypropylene composite had the best thermal stability.The differential scanning calorimetry results of the composites showed that the crystallization rate and crystallinity of the composites were improved by adding appropriate amount of silane coupling agent.关键词
