Abstract

The degradative effects of sulphuric acid on .glass fibre composites with different layup sequencing were studied by monitoring the changes in the Inter Laminar hear Strength (ILSS) using short beam shwr specimens. The composite specimens used or the diffusion studies in Part I were chosen for the degradation studies. The results of he' studies indicated that isopthalic polyester resin composites retained maximum percentage of Inter Laminar Shear Strength, while those of the General Purpose Resin showed higher degradation. The degradation increased as the concentration of the sulphuric acid was increased, indicating at degradation was a dominant phenomenon at higher concentrations. The weave compactness of woven roving type glass-.reinforcement which formed the face skin in the case of composites of sequential layup. A caused higher degradation.
