TEST PIECE FOR COMPRESSION TEST, AND REPETITIVE STRESS FATIGUE TESTING METHOD OF COMPRESSION-COMPRESSION CYCLE

摘要

PROBLEM TO BE SOLVED: To provide a test piece for a compression test capable of reducing a bad influence on a measurement result caused by buckling, when compressing the test piece containing a strip-like fiber-reinforced composite material plate in a lengthwise direction at a testing time; and to provide a repetitive stress fatigue testing method of a compression-compression cycle using the test piece for the compression test.;SOLUTION: In a test piece for a compression test, a first part 10a and a second part 10b on both sides excluding a center part in a lengthwise direction of the test piece 10 containing a strip-like fiber-reinforced composite material plate 16 are inserted into a first shell 12 and a second shell 14 respectively, and the first part 10a and the second part 10b inserted into the first shell 12 and the second shell 14 of the test piece 10 are fixed by stationary portions 22, 24 comprising cured objects of a thermosetting resin.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
