PURPOSE:To provide a sufficient strength for actual use by arranging long fibers along a line connecting center of a large edge part and the center of a small edge part and along each outer periphery of the large edge part, small edge part, and a rod part, in a metal or resin matrix. CONSTITUTION:Long fibers 4 are arranged on each outer periphery of a large edge part 1, small edge part 2, and a rod part in a matrix, and long fibers 5 are arranged on the line connecting each center of the large edge part 1 and the small edge part 2. By arranging long fibers as described in the above, each sufficient strength can be provided for the compressive force, bending stress, and the tensile strength which are applied, during a connecting rod is used, by use of a small amount of fiber. The fiber which possesses high strength and high modulus, such as alumina fiber, carbon fiber, silica fiber, silicon carbide fiber, boron fiber, etc., are desirable as strengthening material. The resin which possesses a high heat resistance at 200 deg.C such as epoxy resin, polyamide resin, polyimide resin, polyamide imide resin, polyether sulfone, etc., and metals such as aluminum, aluminum alloy, magnesium, magnesium alloy are suitable for the matrix material. |
