Document Type and Number:
Japanese Patent JP2686340
Kind Code:
B2
Abstract:
The procedure of the present invention may be applied to mold a composite material having a predetermined configuration. The first step of the present procedure is to form the dimples of the core in accordance with a super-plasticizing molding procedure, so that the dimples may exhibit a height higher than that in its final configuration which corresponds with the above-described predetermined configuration, and its top surface is formed in a convexed configuration. Then, pressure is applied to the core to flatten it by forcibly deforming it prior to or at the moment of jointing the skins of the predetermined configuration, so that the dimples may come into contact with the internal surface of the skin at their top surfaces. Thereafter or simultaneously with this operation, the skins of the predetermined configuration are jointed. The composite material formed exhibits an increased operational reliability and an improved dimensional precision in its configuration, without causing the dimples top surface to be out of contact due to a design allowance.
