The invention proposes a method for manufacturing a grille for a cascade type thrust reverser, of a jet engine, said method including the following steps: a) manufacturing a first component comprising continuous or long fibres, pre-impregnated by a thermoplastic or thermosetting resin; b) manufacturing, subsequently or together with step a), a series of second components each including discontinuous fibres, pre-impregnated by a thermoplastic or thermosetting resin, step b) being carried out such that the second components are, on the one hand, arranged transversally with respect to a longitudinal direction of the first component on at least one side of the first component and, on the other hand, spaced from one another according to this longitudinal direction, so as to form a comb-shaped structure, wherein the second components are consolidated to the first component.

Disclosed herein are systems and methods for manufacturing a part. An example method comprises heating a consolidated laminate sheet, comprising multiple plies each made of fibers embedded in a thermoplastic resin, to a heated temperature below a melting temperature of the thermoplastic resin to form a heated consolidated laminate sheet. The method also comprises forcing the heated consolidated laminate sheet against a contoured forming surface of a mold until a shape of the heated consolidated laminate sheet corresponds with a contoured shape of the contoured forming surface of the mold.

The invention relates to a battery housing (1) for an electrical battery, comprising a basic body (2) which extends in a direction of extent (E) and at least partially delimits a housing interior space (3) on the inside.

The core comprises a membrane, delimiting a containing space shaped to form the cavity, and at least one connector engaged with the membrane. The method includes wrapping a charge of material to be molded around the core, fixing the core inside one between the first and the second half molds, and filling the containing space of the membrane with a filling material. After closing the half molds, applying a molding pressure and then emptying the containing space of the filling material and, after opening the half molds, removing the core from the molded monolithic component.

A system for forming an article includes a polymer resin formulation formed of a semicrystalline polymer material having a first fiber content and an amorphous polymer material having a second fiber content. The first fiber content is higher than the second fiber content. Further, the semicrystalline and amorphous polymer materials are blended together to form the polymer resin formulation having a blended fiber content of greater than 10% by weight. Moreover, the polymer resin formulation is amorphous. The system also includes a computer numeric control (CNC) device for printing and depositing the polymer resin formulation layer by layer to form the article.

Composite structures and methods of forming composite structures are provided. The composite structures can include one or more composite structure components. Each composite structure component is formed from a composite panel that includes one or more sheets of material. The sheets of material include a thermoplastic material and a plurality of reinforcing fibers. A composite panel can be formed in three dimensions to form a composite structure component. Multiple composite structure components can be fused to one another to form a composite structure. In addition, each composite structure component and the composite structure formed therefrom can include an aperture. An interior volume can be formed between adjacent composite structure components. Methods for forming a composite structure can include a step of simultaneously molding and fusing composite structure components.

A method of recycling glass fiber-reinforced polymer composite materials that can provide improved quality recycled glass fiber is described. More particularly, the method comprises pyrolysis of glass fiber-reinforced polymer composite scrap and/or end-of-life material and the subsequent immersion of the pyrolyzed glass fibers in a molten salt bath, e.g., comprising molten potassium nitrate. Immersion in the molten salt bath can eliminate char from the pyrolyzed fibers, as well as removing residual inorganic materials. In addition, immersion in the molten salt bath can strengthen the glass fiber, which can result in the recovery or avoidance of tensile strength losses normally incurred through traditional char removal processes.

A composite component may be additively manufactured by a system that mixes a fiber and matrix and extrudes a body made of the fiber and matrix toward a work piece. The extruded body may be pressed against the work piece and the workpiece and/or extruded body may be moved relative to the other. The extruded body may at least partially melt and flow, uniting with the workpiece and additively manufacturing a layer of a feature thereon. In this manner, friction stir additive manufacturing of composite components having a fiber and matrix composite may be accomplished.
