CFRP積層材の静的横せん断特性

抄録

The first experiment for obtaining the static transverse shear modulus and failure strain of CFRP Laminates is presented in this paper. In order to obtain these values, the difference in vertical displacement of two points on the neutral axis of a short beam specimen is measured by a newly devised electro-optical extensometer. The transverse isotropy is first confirmed by our proposed method. Furthermore, the experimental results of transverse shear modulus and failure strain are compared with those based on a classical lamination theory and a three dimensional FEM code, respectively.
