<p>PURPOSE:To enhance a yield by reducing a thin-walled part of an end part in the molding of a laminate. CONSTITUTION:A resin content in a predetermined-width end part 1 of a prepreg 2 is larger than that in the other part, i.e., a center part 3. At all the periphery, i.e., all the four edges, of the prepreg 2, the predetermined-width end may contain a resin amount larger than the other part, or at part of the periphery, i.e., 1-3 edges, the predetermined-width end may contain a resin amount larger than the other part. But, when the predetermined-width end at part of periphery contains a resin amount larger than the other part, the prepregs 2 are overlapped in different directions so that larger-resin content edges of any of the prepregs 2 exist in every edge of the overlapped prepreg construction. For example, with the use of a prepreg produced with a larger resin content only at only two edges in its width direction, the prepregs 2 are overlapped in different directions by 90 degrees, alternately. The construction made of the prepregs 2 having a larger resin content in a fixed-width end at its 1-4 edges is press molded.</p> |
