摘要

This paper is concerned with the influence of argon plasma on the interfacial adhesion of PBO fiber/bismaleimide composites and aging behaviors. The interlaminar shear strength (ILSS) was greatly increased to 62.3 MPa with an increase of 39.7% after treatment for 7 min at 80 Pa, 200 W. A small amount of 0 and N atoms was incorporated onto the fiber surface, but the plasma caused C-0 bonds to break and generated O=C-N groups. The fiber surface roughness increased, contributing much to the wettabil-ity. However, long-time treatment excessively destroyed the inherent and newly created structures. The SEM images suggested that the fracture shifted from the interface to the matrix. The modification effects degraded with storage time in the air and the ILSS decreased to approximately 54.0 MPa after 10-30 days. The composite had low water absorption of 2.0 wt% and a high retention of 90% in the ILSS at moisture conditions.
