Abstract

See full text

The present application relates to a method of injection molding a resin such as a RTM mold. The method enables to manufacture a composite part comprising a resin body and a sheet or strip, forming a surface of the composite part. The composite part can be an annular compressor casing of an axial turbomachine, with a composite annular wall. The method includes the steps of: (a) placing and holding the sheet against a mold surface by fastening means such as welds or microwelds; (b) injection and solidification of the resin in the mold so as to form the body by binding it to the sheet; (c) release of the sheet by the fastening means when a release force is exerted on the composite and release part of the composite part.
