Document Type and Number:
Japanese Patent JP4526698
Kind Code:
B2
Abstract:
A composite material-stiffened panel (1) has a skin (2) obtained by molding a fiber-reinforced resin composite material into a flat skin, stiffeners (3) arranged in rows on one surface of the skin (2), and a fiber-reinforced resin-composite material (4) stitched on the skin covering the stiffeners (3). The composite material-stiffened panel can be manufactured as follows: A first fabric material (2) is placed on a tool having a panel-shaped surface. Stiffeners (3) are placed on the first fabric material (2). A second fabric material (4) is placed on the stiffeners (3) to cover at least some of the stiffeners. The second fabric material (4) is reformed to match the shape of the stiffeners (3). The reformed second fabric material (4) is stitched on the first fabric material (2) along edge of the stiffeners (3). All the materials are covered with a bagging film for vacuum. Resin is infiltrated into the fabric materials by a RTM or a RFI method. The infiltrated resin is heated to be hardened.
