<p>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 test piece 1 for a three-dimensional composite material, the whole is formed in a rectangular parallelepiped shape by a resin 2, fibers F in three directions of X, Y and Z are disposed mutually orthogonally along each surface C-Cthereof, and the fiber in each direction allows its cut surface F1 to face to each face. In a production method, after disposing each fiber in the three directions of X, Y and Z and injecting a resin thereinto, regions A, Aincluding at least fibers on the uppermost layer and the lowermost layer in the X, Y directions are removed.</p> |
