The present study has been conducted because of the absence of previous studies on the stress and the fracture of FRP angle ply laminates with a fastened pin joint. The following became evident after examing results from 3-D FEM stress analysis and by experiments on three practical GFRP angle ply laminates. (1) The distribution of each stress component, the maximum shear stress and their concentration in each reinforced lamina which is oriented at 0゜, ±45゜and 90゜ to the tensile loading axis and in the very thin matrix layer. (2) The effect of the fastening force to the reinforced lamina and the matrix layer. (3) Posibility of estimation of the fracture strength and the mode of the fracture of the fastened pin joint laminates applying some proposed fracture criteria using stresses by FEM analysis.
