Abstract: Composite materials consisting of stiff and strong fibers (glass, carbon, Kevlar, etc) reinforcing a compatible matrix (polymers, metals, ceramics, carbon, etc) in the form of a laminate are engineered materials. This paper presents the results of an investigation into stress analysis and progressive failure analysis (first ply failure to last ply failure) of a laminated composite annular disc made up of glass epoxy and graphite epoxy subjected to spinning. The ANSYS software and its powerful analysis, pre and post-processing capability is exploited to graphically present contour plots of ply by ply stresses in the material co-ordinates and Tsai-Wu failure index.
