On the Design and Optimization of Bidirectional Composites

Abstract

The intention of this report is to help develop a feeling for the directional properties of laminated composites. Simple rules for the versatile application of anisotropic, though orthotropic bidirectional laminates are presented. Simple examples and charts demonstrate the possible weight advantages over quasi-isotropic configurations. Ex plicit use is made of the Mohr's circle representation. Multiple loading is considered and a graphic solution is indicated.
