摘要

Two methods including coupling agents after argon plasma and coupling agents before argon plasma were employed to modify the poly[1,4-phenylene-cis-benzobisoxazole] (PBO) fiber surface. The surface properties of PBO fibers were comparing treated by two methods of Coupling Agents before Argon Plasma and Coupling Agents after Argon Plasma. The interfacial shearing strength (IFSS) of PBO fibers/epoxy resin was measured by the single fiber pull-out test. The surface morphology and the wettability of PBO fibers were determined by scanning electron microscopy and . Washburn method. The results showed that the wettability of the treated fibers were improved. Under the same concentration of the coupling agents and the same parameter of argon plasma, the IFSS of PBO fibers treated by coupling agents before argon plasma (PBO-A-187-Ar) was always larger than that of PBO fibers treated by coupling agents after argon plasma (PBO-Ar-A-187). The IFSS of the untreated fibers was 5.88MPa, while at a 2% concentration of coupling agents (A-187), the highest IFSS of PBO-A-187-Ar and PBO-Ar-A-187 were 10.44MPa and 9.30MPa, respectively.
