    Abstract

    Multidirectional (M-D) fiber-reinforced plastics (FRP) of isotropic strength have been developed utilizing a fluidized bed. Tension, compression, and bending tests were carried out on these M-D FRP, and their fracture modes also were examined paying special attention to the surface of crack initiation. Based upon the results obtained, an improvement of the strength of these composite materials was tried by retreatment of the cut end-surface of strands and use of appropriate ductile matrix. Thus we obtained an object of considerable satisfying strength.
