摘要
以超高分子量聚乙烯纤维布为处理对象 ,研究了紫外接枝处理过程中各种因素对处理后复合材料层间剪切强度的影响 ,发现以丙烯酰胺为接枝单体时的处理效果最好 ,并用扫描电镜、红外光谱以及 XPS研究了纤维处理前后表面性能。
Factors in the process of UV photo-initiated grafting treatment of UHMWPE fibers woven and their effects on the inter-laminar shear strength of composites are discussed. The inter-laminar shear strength (ILSS) of composites was used to characterize the treatment effect. The results show that UV photo-initiated grafting acrylamide is the best. After treatment, the ILSS of composites is increased up to 18.85 MPa, almost twice that of untreated. The surface properties and morphologies of UHMWPE fibers before and after treatment were studied by SEM, FTIR and XPS.
