PROBLEM TO BE SOLVED: To provide a compression test jig in which a load axis and a strand axis of a compression test piece can relatively simply be aligned and a compressive-strength of a resin impregnated strand can be evaluated with high accuracy, provide the compression test piece in which adhesive resin is hard to be deposited on the compression test part when making the test piece and the resin-impregnated strand is easy to be fixed to a tab, and provide a compression test piece making jig and a compression test method.;SOLUTION: A compression test jig 2 has a pair of platens 11 including a gripper 21 for gripping and fixing the side faces of tabs 11. A compression test piece 1 holds both ends of a resin impregnated strand 10 by the pair of tabs 11. The tabs 11 have through-holes 111 and communication holes 112. Adhesive resin 12 is filled in the communication holes 112 between an outer circumferential surface of the resin impregnated strand 10 and an inner circumferential surface of the through-holes 111. A compression test piece making jig 3 has a guide part 31 for separating a base part 30 and the multiple tabs 11 from each other and arranging them in one direction, and a fixing part 32 for pressing and fixing the tabs 11 to the guide part 31.;SELECTED DRAWING: Figure 16;COPYRIGHT: (C)2019,JPO&INPIT
