Composite part i.e. composite casing, for turboprop engine of aircraft, has embossing element whose fibrous reinforcement is traversed by multiple pins that are extended from reinforcement of ring shaped structural body

摘要

The part has multiple embossing elements placed on a surface of a ring shaped structural body. The embossing elements and the body comprise respective fibrous reinforcements (120, 130, 160) densified by a matrix. Each reinforcement is traversed by multiple pins (122, 132), where the pins are extended from the reinforcement of the body. The reinforcement of the body is formed of a multi-layered woven layer between a warp thread layer and a weft thread layer. The pins are formed of continuous filaments impregnated with polymerized resin. An independent claim is also included for a method for fabricating a composite part.
