Coupling for composition structural component such as aircraft under carriage strut is made by separating primary fiber plies and inserting separator plies

摘要

The procedure for making an end coupling for a structural component of a composition material such as carbon fibers and polymerised resin having at least one extension (113) to form the coupling consists of separating the primary fiber plies (N1 - N7) and inserting separator plies (116) between them. The fibers of the separator plies lie obliquely relative to the weft fibers of the primary plies in the extension zone, and transverse fibers (117) are inserted across the primary and separating plies. The width of the separating plies increases the width of the extension, which is pierced to form the coupling eye after resin injection and polymerisation.
