The present study investigates ultimate failure of hybrid thin-ply laminates. Hybrid laminates were manufactured from layers of carbon fiber and glass fiber fabrics using vacuum infusion of epoxy resin. Different lay-up configurations having single, double and quadruple layers of carbon and glass fiber layers were designed to parametrically investigate the ultimate strength and strain to failure under uniaxial tensile loading. In addition laminate specimens were polished to study the micro-damage mechanisms in the laminate layers. Results indicate an increased tensile strength and strain to failure when carbon and glass/epoxy layers are distributed into thinner layers compared to laminates with equal amount of carbon and glass/epoxy layers assembled into thicker layers.
