Compressive Behaviour of Unidirectional Glass/Carbon Hybrid Laminates
Experimental data on the compressive strength of glass carbon hybrids are presented. Carbon/glass ratios of 0, 12.5, 25, 37.5, 50, 75 and 100% were tested in 1 and 2mm thick unidirectional laminates. It was found that lower strength was obtained with carbon plies on the surface of the specimen. 8-ply were found to be stronger than 16-ply specimens, a result confirmed by a finite element investigation of the specimen stress distribution. The rule of mixtures was found to give a good estimate for hybrid modulus, provided the stiffness of the constituents was taken at the appropriate strain level.
