Zanchor法によるCFRP積層材の層間高じん化

抄録

The capability of using Zanchor technique in improving interlaminar fracture toughness has been clarified. However, since the object of evaluation was restricted within brittle matrix, it is necessary to clarify the utility of Zanchor technique for different material properties. Therefore, it was revealed that the Zanchor technique for tough matrix and quasi-isotropic laminates prepared by RTM affects various mechanical properties including increasing the interlaminar fracture toughness. The results suggested that the effect of improving the mode I interlaminar fracture toughness for CFRP laminates with tough matrix was more effective than brittle matrix. In addition, the effect of improving the mode I interlaminar fracture toughness for quasi-isotropic CFRP laminates was more effective than cross ply.
