Structural foam molding method using continuous fiber composites, and parts formed therefrom

A method for making structural foam parts having continuous aligned fibers includes placing an assemblage of fiber-bundle-based preforms in an injection mold, creating a melt flow of resin and, optionally, short, loose fiber, and adding foaming agent to the melt flow. When the foaming agent/melt flow mixture is introduced into the injection mold, the foaming agent foams. The assemblage is structured and positioned so that fibers therefrom adopt a desired alignment and position in the final part. Structural foam fills the remainder of the volume of the part.

Process for manufacturing composite articles

The present invention relates to the use of thermoplastic polymer compositions for impregnating reinforcing materials in the form of fabric or industrial fabrics for the manufacture of composite materials. The field of the invention is that of composite materials as well as molding/consolidation processes and obtained parts. The invention more particularly relates to a method of manufacturing a composite article by injection molding comprising at least the steps of introducing at least one reinforcement fabric into a preheated mold, partial closure of the mold, a temperature rise step of the mold, optionally a step of maintaining the temperature of the mold before injection of a thermoplastic polymer composition, a step of injecting a thermoplastic polymer composition into the mold, a step of mold closure to the final part thickness allowing the flow of the resin through the reinforcing fabric, a cooling step and a recovery step of the obtained composite article.

11616430 · 2023-03-28 ·

A Magnetic Gear Modulator (MGM) of a Concentric Magnetic Gear (CMG) is manufactured by injection molding a modulator cage over angularly spaced apart MGM pole pieces made of a magnetically conducting material. The pole pieces are initially connected by a support ring, or held by a fixture. The modulator cage is preferably a thermally conductive strengthening fiber filled plastic, a carbon fiber plastic, a carbon fiber filled plastic material, a glass material, or a high performance composite plastic molding material. After molding, the outer and/or inner portions of the molding material, and support ring if present, are machined away preferably exposing both inner and outer faces of the pole pieces embedded in the modulator cage. An MGM made using injection molding over a connected support ring and pole pieces reduces cost, and a carbon fiber plastic modulator cage increases strength.
