パッチを用いて成型されたCFRTP積層材の数値剛性評価

抄録

This paper presents the numerical stiffness evaluations of CFRTP composite laminates 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 calculation the 3-point bending problem is picked up, and the deformations and the bending stresses are obtained numerically. The stiffness of the laminates is thus discussed from the numerical results.
