A method for overmolding a thermoplastic tip onto a hollow profile member made of thermosetting composite and to an assembly including a thermosetting profile member and a thermoplastic tip, wherein it includes machining the shape of the profile member made of thermosetting composite on the injection region; positioning a cap in the profile member; thermally conditioning the profile assembly and the cap; and injecting the tip with thermoplastic composite in order to create the junction of the profile member, the cap and the tip.

A method for making a bicycle crank arm includes (a) providing an inner frame unit, (b) winding a first bundle of unidirectional continuous fibers on the inner frame unit to form an intersecting pattern, (c) impregnating the intersecting pattern with a curable resin material to obtain an impregnated structure, and (d) molding the impregnated structure in a mold.

A tooling for winding a fibrous fabric on a support, allowing gradual modification of the shape of the support as winding progresses, and includes compaction devices to reduce wrinkling of the fabric obtained after compaction.

Some embodiments are directed to a method for overmolding a thermoplastic tip onto a hollow profile member made of thermosetting composite and to an assembly including a thermosetting profile member and a thermoplastic tip, wherein it includes machining the shape of the profile member made of thermosetting composite on the injection region; positioning a cap in the profile member; thermally conditioning the profile assembly and the cap; and injecting the tip with thermoplastic composite in order to create the junction of the profile member, the cap and the tip.

A suspension arm includes: a vibration-proof bush including tubular fittings, a tubular elastic member formed on an outer periphery of the tubular fittings, and a resin band that is wound around an outer peripheral surface of the tubular elastic member and imparts a pre-compression in a radial direction of the tubular elastic member; and a resin arm fixed to the vibration-proof bush by integrally forming a resin material so as to surround the outer periphery of the vibration-proof bush.
