Experimental examination of the special features of deformation and failure in tensile loading of cross-reinforced wound composites

1. The width of the wound tape and the “degree” of interweaving of the tapes have no effect on the elastic characteristics of the glass fiber-reinforced epoxy wound plastic with the reinforcement angle ±45°. 2. The increase of the reinforcement factor increases the elasticity modulus whose value may be calculated with sufficient accuracy by the methods of the structural theory of composites. 3. The width of the wound tape influences the strength of the composite; the reduction of the width of the tape increases strength. 4. An increase of the “degree” of interweaving of the tapes reduces the strength in axial tensile loading; the zones of interweaving represent the “weak member” of the composite. 5. The variation of the reinforcement factor in the examined range has a strong effect on the strength of the composite. This is associated with the variation of the thickness of the interlayer of the binder between the wound tapes.
