Abstract
【解決手段】部品の層に対応するプリプレグテープを積層することにより部品のプリフォーム30を形成する。各々のテープは、マトリックス前駆体、結合材、及び繊維要素32列を含有している。これらのテープを積み重ねて、少なくとも第1のテープの繊維要素32が屈曲部34を横切り、繊維要素32が屈曲部34の湾曲の軸36に対して垂直ではない平面38、40内にあるようにする。次いで、プリフォーム30を熱加工する。その間、繊維要素32が屈曲部34の湾曲の軸36に対して垂直な平面内にないことの結果として、屈曲部34内の層の層間剥離が抑制される。

Description
ガスタービンエンジンの効率を高めるために、より高い作動温度が絶えず求められている。鉄、ニッケル及びコバルト基超合金の開発を通して高温能力の飛躍的な進歩が達成されているが、代替材料が研究されて来ている。セラミック材料及びセラミックマトリックス複合(CMC)材料は、その高温能力により冷却用空気に関する要件を大幅に軽減することができるので注目に値する例である。CMC材料は一般に、セラミックマトリックス材料内に埋め込まれたセラミック繊維強化材を特徴とする。この強化材は、マトリックス材料内に分散した不連続の短繊維又はマトリックス材料内で配向された連続繊維若しくは繊維束であり得、CMCのマトリックスに亀裂が発生した際に負荷を担う構成成分として機能する。一方、セラミックマトリックスは強化材を保護し、その繊維の配向を維持し、強化材に対する負荷を消散する役目を果たす。
