Radial reinforcement of thick-walled rings of composite materials

Polymer Mechanics Aims and scope

Abstract

The possibility of improving the resistance to internal pressure of thick-walled rings with circumferential reinforcement by introducing radial or axial reinforcement has been investigated in the first approximation. Axial reinforcement is considered in relation to the use of combined (unidirectional + fabric) materials. On the basis of hypotheses concerning the homogeneity and linear-elastic behavior of the material and simple fracture criteria numerical estimates are obtained for the relative efficiency of the reinforcement scheme, the optimal material structure, and the corresponding ranges of relative thickness of the rings. The qualitative conclusions are compared with experiments on rings of combined material.
