The purpose of this paper is to investigate the effect of the specimen geometries on the pin bearing strength of the angle ply carbon fiber reinforced composites. The effect of the edge distance and the specimen width on the pin bearing strength of angle ply CFRP composites are experimentally investigated in this paper. As results, the failure mode and pin bearing strength of mechanical joints turned out to depends on the stacking sequence and specimen geometries such as the edge distance and the specimen width. The higher pin bearing strength obtained for the angle ply CFRP composites is attributed to a combination of debonding, pull out, buckling and breakage of fiber and also the matrix cracking.
