STUDY ON SURFACE MODIFICATION OF PBO FIBER AND ITS INTERFACIAL PROPERTIES WITH RESIN MATRIX

Abstract

Abstract: Two different surface treatment methods, single treatment process (such as “chemical treatment”, “plasma treatment”, “coupling treatment” and “radiation treatment”) and combined treatment processes (such as “radiation & plasma treatment” and “radiation & plasma & coupling treatment”) were used for the surface modification of PBO fiber, respectively. Then, the tensile strength, contact angles and interface bonding strength of the treated fibers were tested. The results show that, PBO fibers treated by the combined ways have better integrated properties: the residual tensile strength is about 85.1% of the untreated fiber; the contact angel between the treated fiber and water is 74.15°; the bonding strength between combined treated fiber with epoxy resin is 48.6% higher compared to the untreated fiber.

Key words: PBO fiber, surface modification, interfacial properties
