摘要： 由高强聚乙烯纤维制成的复合材料抗高速撞击(抗弹)性能远远优于芳纶纤维,广泛用作各种防弹材料.而且它的透波性很好,用这种复合材料制造的雷达罩比玻璃钢雷达罩透波率高15%.此外,高强聚乙烯纤维复合材料在海洋工业、体育用品等各方面也有广泛的应用.

Abstract: High-strength polyethylene fiber (Dyneema SK60) was surface modified through cold air plasma treatment. Poly(acrylic acid)(PAA)and poly(acrylic acid-co-ethyl acrylate) (P(AA/EA)) were grafted onto plasma activated Dyneema SK60 fibers. Fiber interfacial properties were studied with a single fiber pull-out test. The stated surface modifications evidently improved the interfacial adhesion and increased the interfacial fracture energy of the Dyneema/epoxy composite system.

Key words: high strength polyethylene fiber, plasma, surface modification, interfacial property
