Abstract

In the present work residual stresses in a boron fibre/aluminium matrix composite are determined through an etching method. The inhomogeneous removal of surface layers, due to the different sensitivity of boron and aluminium to alkaline environment, requires the application of a modified technique for the estimation of deformations and the calculation of stresses. The results obtained indicate considerable deviations in both distribution and magnitude of residual stresses in the same MMC, due to different fabrication methods.
