Description
3次元織りにより単一繊維素材を形成すること;
前記繊維素材を造形して、羽根板翼及び羽根元の予備成形物を形成している第1部分と、内方又は外方羽根プラットフォームの為の予備成形物を形成している少なくとも1つの第2部分と、を有している単一繊維予備成形物を得ること;そして、
この予備成形物を母材で高密度化し、この予備成形物により構成されていて母材により高密度化されている繊維強化材を有していて、組み込まれた内方及び/又は外方プラットフォームを伴った単一部位を形成している複合材料羽根を得ること、
を備えている、
母材により高密度化された繊維強化材を備えている複合材料からターボ機械羽根を製造する方法を提供する。
複合材料を非脆化(non-brittle)するその機能を果たすのに十分な厚さを提供している繊維―母材中間相を全体に得る為に、第2中間相層(second interphase layer)がCVIにより形成された(工程511)。第2中間相層はPyC,BN,そしてBCから選択された材料であって良く、そして第1中間相層の材料と必ず同じ材料である必要がない。第2中間相層の圧さは好ましくは100nm以上である。
