PROBLEM TO BE SOLVED: To provide a composite pressure bulkhead for use in a vehicle, and methods of manufacturing such a composite pressure bulkhead.SOLUTION: A pressure bulkhead 10 employs a plurality of layers of composite fiber material having unidirectional fibers arranged in a single direction within the composite fiber material. The pressure bulkhead incorporates non-traditional radial and circumferential stiffening members 22, 28 into a composite laminate 30 and aligns the radial stiffening members 22 with the direction of dominant load paths. The radial and circumferential stiffening members are interlaid between full layers of the composite fiber material. Related methods of manufacturing the pressure bulkhead include using automated fiber placement equipment to form each layer of the pressure bulkhead and discretely orient integral stiffeners and unidirectional fibers in each layer.SELECTED DRAWING: Figure 2

    【課題】ビークルで使用するための複合材圧力隔壁、及びこのような複合材圧力隔壁を製造する方法を提供する。【解決手段】圧力隔壁10では、複合繊維材料内で単一方向で配置された一方向繊維を有する複合繊維材料の複数の層が利用される。圧力隔壁では、従来なかった半径方向及び周方向の補強部材22,28が複合材積層板30に組み込まれ、半径方向補強部材22が主要荷重経路の方向と整列させられる。半径方向及び周方向の補強部材は、複合繊維材料の全層の間に介在する。圧力隔壁を製造する関連方法は、圧力隔壁の各層を形成し、且つ一体型補強材及び一方向繊維を各層で不連続的に配向するために自動繊維配置装置を使用することを含む。【選択図】図2
