摘　　要：为了改善高强高模聚乙烯纤维与环氧树脂的粘接性，通过电子预辐照接枝工艺对ＰＥ纤维表面进行改性。试验发现，在Ｎ２气氛下电子预辐照接枝反应工艺并不需要引发剂，随着预辐照剂、反应温度和反应时间的增加，反应接枝率增加。In order to improve the surface adhesion of high strength and high modulus polyethylene(PE) fibers with epoxy resin, graft polymerization of some monomers by electron beam(EB) pre-radiation was performed on the surface of PE fibers. In the paper, the Van de Graff accelerator was chosen as a radiation resource. And we found from our studies that no sensitiaer was needed in EB pre-radiation polymerization under the atmosphere of N2 and acrylic acid was most effective in the polymerization of methyi methacrylate, acrylic acid and methacrylic acid. The degree of graft incrased with the enhancing of pre-radiation dose, reaction temperature and reaction time. Acetone and benzene were effective solvents for acrylic acid. Oligomer, which exists during the polymerization, could be removed by washing with benzene. Grafted fiber was analyzed by SEM and ATR-IR and it was confirmed that some polar groups were introduced to the surface of PE fiber. The tensile strength of PE fibers did not decrease greatly when pre-radiation dose was less than 1.56 × 10Gy.
