Properties of Kevlar Fibers by Surface Modification

Abstract:

The surface of Kevlar fiber was modified by hydrogen peroxide solutions (H₂O₂) in this article. The interfacial properties of Kevlar fiber/epoxy composites were investigated by the single fiber pull-out test (SFP). The results showed that the interfacial shear strength (IFSS) of Kevlar /epoxy composites was remarkbly improved after surface modification and the breaking strength has not been affected appreciably. It provided an efficient method to make the surface modified Kevlar fiber for the application for the advanced composites at a lower production cost.
