A Microdebonding Test for In-Situ Fiber-Matrix Bond Strength and Moisture Effects,

Abstract

The paper describes a test technique which gives a quantitative measure of the in-situ fiber/matrix bond strength in composites. The test involves the compressive loading of a fiber or region of fibers on a polished specimen surface to produce debonding. Results are given for the debonding load for glass, aramid and graphite/epoxy composites. The change in debonding load is also followed as the interface degrades during moisture conditioning at different points through the thickness. Refinements are needed to simplify interpretation of the debonding force in terms of interface shear strength, and to make the test more reproducible. jg p4
