COMPOSITE MATERIAL REINFORCING PART OF PI-SHAPED SECTION, IN PARTICULAR A PLATFORM FOR A TURBINE ENGINE FAN, AND ITS METHOD OF FABRICATION |
摘要 |
A reinforcing part of π-shaped section made out of composite material, and a method of making the part, the method including: making a first set of layers of interlinked yarns by three-dimensional weaving to form a first fiber blank portion to form a base preform; making a second set of layers of interlinked yarns by three-dimensional weaving to form a second fiber blank portion to form a stiffener preform, yarns of the second set being interlinked with yarns of the first set by weaving over a central interlinked strip that flares towards side edges of the first fiber blank portion in a zone corresponding to the step of the base; shaping the two fiber blank portions to obtain a single-piece fiber preform having a portion forming a base preform and a portion forming a stiffener preform; and depositing a resin in the fiber preform to form a matrix. |
