【Abstract】 In this paper, factors in the process of plasma treatment to UHMWPE fibers woven were discussed. The inter-laminainar shear strength (ILSS) of composites was enhanced from 5.98 MPa to 18.1 MPa by plasma treatment. The radicals produced were generated about 14.4×10 -7 mol/g on the surface, which were measured by DPPH method. The surface properties and the morphologies of UHMWPE fibers before and after treatment were studied by XPS and SEM .更多还原
