PRODUCTION METHOD OF TEST PIECE FOR THREE-DIMENSIONAL COMPOSITE MATERIAL, AND TEST PIECE FOR THREE-DIMENSIONAL COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a novel test piece for a three-dimensional composite material capable of measuring a tensile characteristic or the like of the three-dimensional composite material more accurately than hitherto, and to provide a production method thereof.;SOLUTION: In a production method of a test piece 1 for a three-dimensional composite material, first fibers F functioning as reinforced fibers are disposed as much as a plurality of layers respectively in the X, Y directions, second fibers f having a small elastic modulus are disposed on the upper and lower sides thereof in the X, Y directions, and after allowing layers of the fibers F, f in the X, Y directions to penetrate, disposing the first fibers F also in the Z direction and injecting a resin thereinto, regions A₁, A₂ are removed, which include the second fibers f on the uppermost layer and the lowermost layer in the X, Y directions and folded parts of the first fibers F in the Z direction.;COPYRIGHT: (C)2015,JPO&INPIT
