TENSILE STRENGTH TESTING METHOD OF FILAMENT-REINFORCED METAL MATRIX COMPOSITE MATERIAL AND TENSILE TEST PIECE

摘要

PROBLEM TO BE SOLVED: To provide a tensile strength testing method of a filament-reinforced metal matrix composite material capable of stably and precisely performing a tensile strength test.;SOLUTION: The tensile strength testing method is a method to test on a filament-reinforced metal matrix composite material in the longitudinal direction, in which plural high strength continuous filaments (12) are disposed adjacent to the central axis thereof along a longitudinal direction of a rod-like matrix metal (11). The rod-like matrix metal (11) has a parallel portion (13) where a part in the longitudinal direction is reduced in thickness and a pair of grip portions (14) formed at both outer end portions interposed by the parallel portion (13) therebetween. After gripping the grip portions (14) with chucks of the test machine, the parallel portion (13) is pulled by separating the chucks away from each other. The high strength continuous filaments (12) are extended from both outer ends of the grip portions (14) being fixed thereto.;COPYRIGHT: (C)2014,JPO&INPIT
