    METHOD FOR PRODUCING PREPREG SHEET FOR PRESSURIZATION-HOT MOLDING OF 2D-CERAMIC FIBER-REINFORCED COMPOSITE MATERIAL WITH CYLINDER SHAPE

    New search for: KAYAMA AKIRA

    To suppress characteristic deterioration caused by thread breakage in reinforcing ceramic fiber as a component of prepreg sheets as an intermediate stock for producing a ceramic composite material upon molding by heating-pressurization by molding a preform according to the lamination of the prepreg sheets.SOLUTION: A prepreg sheet as an intermediate stock for producing a ceramic composite material is subjected to corrugation working (corrugation shape application), and the same is laminated to mold a preform, thus the thread breakage of reinforcing ceramic fiber caused by volume shrinkage in heating-pressurization is suppressed.SELECTED DRAWING: Figure 1

    【課題】セラミック複合材料製造用の中間素材であるプリプレグシートの積層によりプリフォームを成型し、加熱・加圧により成型する際のプリプレグシートの構成要素である強化セラミック繊維の糸切れによる特性劣化を抑制する。【解決手段】セラミック複合材料製造用の中間素材であるプリプレグシートにコルゲート加工（波打形状付与）を施し、これを積層することでプリフォームを成型し、加熱・加圧時での体積収縮による強化セラミック繊維の糸切れを抑制する。【選択図】図１
