A series of experiments are carried out to obtain the fundamental design data on the mechanical joint strengths in the fiber reinforced plastic rocket chambers manufactured by filament winding. First, the three kinds of fundamental joints, that is, bolt or rivet joint, screw joint and insert type of joint, are checked in the cylindrical specimens under tension and compression and then the small models of chambers using bolt joints are checked under internal pressure. As a result, the practical data including various influence factors on the joint strength are obtained which are useful for the design of joints to join the upper and lower stages and to assemble the cylin drical and spherical parts in a chamber. These experimental results will be applied to the design of large FRP chambers for Lambda and Mu rockets which are now being developed in our Institute.
