CFRP複合材料の機械的接合部における面圧強度の非接触測定

抄録

The purpose of this work is to establish a simpler experimental technique, in order to measure the deformation of hole as a basis of defined bearing strength evaluation of composite materials in some testing standards. The practical measurement system has been developed using non-contact Electro-Optical Extensometer which does not require the special attachment device. The accuracy of the present system was verified by a comparison with a strain gauge and clip-on extensometer data. The applications of the present method to the bearing strength evaluation of CF/PIXA composite specimens are carried out. In addition, the experimental results of CF/Epoxy composite materials are also reported to compare with these results.
