尼龙6原位包覆碳纤维布的制备
Preparation of PA6 In-Situ Covered Carbon Fiber Cloth
摘要
Abstract
In this study,N,N dimethylformamide(DMF)impregnation and high-temperature calcination were used to remove the epoxy sizing agent on the surface of commercial carbon fiber cloth(CFC),followed by γ-aminopropyltriethoxysilane(KH550)surface modification of the treated CFC,and then finally anionic in-situ polymerization was used to prepare the composite of nylon 6(PA6)in-situ coated carbon fiber cloth.Scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FTIR),X-ray photoelectron spectroscopy(XPS),and thermogravimetic analysis(TGA)were used to characterize the carbon fiber cloth before and after treatment and the composites of PA6 in-situ-coated carbon fiber cloth,while the effects of the removal method,the surface modification of the carbon fiber cloth by KH550,and anionic in-situ polymerization on the PA6-coated carbon fiber cloth were investigated.The results showed that DMF impregnation while high-temperature calcination treatment could effectively remove the epoxy resin on the surface of commercial carbon fiber cloth,but the effect of high-temperature calcination treatment was significantly better than that of DMF impregnation.The carbon fiber cloth modified by KH550 enhanced its wettability with caprolactam(CPL)melt and was conducive to the all-around encapsulation of PA6 on the surface of the carbon fiber cloth,which effectively solved the problems of uneven dispersion of the carbon fiber cloth in PA6 and poor interfacial bonding.关键词
