Evaluation test of structural properties for CFRP plate with optimized material orientation

Abstract

In this study, the structural characteristics of CFRP plates with an optimal free-material orientation, which was determined by the optimization method in advance, were evaluated by testing, where static rigidity and frequency response characteristics were measured. In addition to the CFRP specimen with optimal material orientation, two types of linear orientation and resin-only specimens were fabricated and tested for comparison. All specimens except for the resin-only were fabricated using Tailored Fiber Placement (TFP) based on a stiching technique. It was confirmed that the CFRP plate fabricated based on the optimal material orientation calculation has the best performance on the rigidity and the frequency response.
