Numerical Structure Analysis for CFRTP Composite Stay Rod by Prepreg Patch

Abstract

This paper presents the numerical structure analysis of CFRTP laminated stay rod made by prepreg patch, which is the CFRTP prepreg sheet cut into small pieces from an usual prepreg sheet. For this purpose, the numerical model is constructed by using the ACP function of commercial finite element analysis software, ANSYS. In numerical calculation the 3-point bending problem is picked up for the laminates, and the deformations, the bending stresses and the bending strains are obtained numerically. The stiffness of the laminates is thus discussed from the numerical results.
