A pad main body is bonded integrally with an inner pad while covering the front side of the inner pad. A back-side reinforced fabric located on the back side of the pad main body and the inner pad is integrally bonded on the back side of the inner pad and the pad main body by impregnation of foamed synthetic resin materials constituting the inner pad and the pad main body. This allows impregnation of the foamed synthetic resin materials in the back-side reinforced fabric located on the back side of the inner pad and the pad main body. This consequently allows providing a high hardness on the back side of the inner pad while ensuring hardness on the back side of the pad main body.

A production method for a fiber-reinforced component according to the present invention includes: a step 1, in which a melt of a thermoplastic resin is formed in a lower die, a mat-shaped material formed from a reinforcing fiber B is placed on the melt, an upper die for pressing is closed on the lower die and is pressed, and an impregnation treatment is performed, and then, the mat-shaped material impregnated with the resin is cooled and solidified, whereby a main body part formed from a fiber-reinforced resin is molded; and a step 2, in which the upper die for pressing is opened, an upper die for injection molding is closed on the lower die to form an injection molding die, and then, injection molding is performed to form an additional part, whereby a fiber-reinforced component having the additional part combined with the main body part is molded.

The present disclosure relates to a process for manufacturing composite articles. and composite articles made thereby. The processes described herein make use of curable compositions containing NCF fabrics having certain types of stitching yarns. The curable compositions and composite articles made according to the present disclosure are particularly suited to the production of composite parts for use in many applications, such as in aviation, automotive, and marine applications.

Certain embodiments described herein are directed to articles that provide less sag. In some examples, the articles can include a fiber reinforced thermoplastic polymer core layer comprising reinforcing fibers and a thermoplastic polymer, and a frim disposed on the fiber reinforced polymer core layer. In certain examples, the frim comprises a film coupled to a scrim comprising an effective basis weight to prevent substantial sag of the article, e.g., during a forming operation.

Compositions and methods for forming epoxy resin systems are provided. In one embodiment, a composition is provided for an epoxy resin system including a liquid epoxy resin component including a liquid epoxy resin and an acrylate monomer, a curing agent component including a compound having an imidazole group and, optionally, a co-curing agent for the compound having an imidazole group comprising a phenolic monomer compound, a branched chain carboxylic acid, and combinations thereof, and a non-aromatic polyol compound. The composition may be used to form composites, such as used in commercial wind turbine blade manufacturing.

Methods for manufacturing three-dimensional fiber fabrics and three-dimensional component preforms include clamping at least two edge regions of an overall convex body made a fiber fabric and then reshaping at least one to-be-reshaped region of the overall convex body into a concave region. Devices for manufacturing three-dimensional fiber fabrics and three-dimensional component preforms include a workpiece carrier for supporting the overall convex body, a clamping device that clamps the at least two edge regions of the overall convex body and a re-molding tool that re-shapes the at least one to-be-reshaped region of the overall convex body into the concave region.

A method of producing a flame resistant ticking includes laminating a flame resistant substrate to a decorative fabric, wherein the substrate is configured to release a chemical vapor that reduces the rate of propagation of a flame along the decorative fabric when the decorative fabric is exposed to flame. The substrate is laminated in direct contact with the inside surface of the decorative fabric. In some embodiments, the laminated ticking is configured to release less than 15 MJ of heat in the first ten minutes when exposed to a flame in accordance with the testing protocol set forth in 16 CFR 1633. Upholstered articles, such as mattresses, mattress foundations, and articles of furniture, may incorporate the flame resistant ticking layer.

The invention relates to a preformed sheet, comprising a network of polyethylene fibers having a tensile strength of at least 1.5 GPa, impregnated with at least 10% of a plastic wherein the plastic material is an acrylic based thermoplastic material with a glass transition temperature of at least 25? C. The invention further relates to an assembly of at least two preformed sheets and to a ballistic resistant article comprising at least one assembly.

An assembly for producing a fiber composite workpiece having a base tool, including a first tool part and a second tool part, arranged relative to one another either in a closed position in which they enclose an internal space, or in an open position wherein a preform can be mounted in the internal space and maintained there in a predetermined shape. The base tool includes a connection to convey matrix material into the internal space, and has a device for holding the first and second tool parts together in a closed position. A tool insert is provided which is separate from the base tool, the tool insert being mounted in the internal space of the base tool, and the tool insert including a cavity for accommodating a preform and a shaping surface, facing the cavity, for maintaining the preform in a predetermined shape.

A mold, a molding apparatus, and a method for manufacturing articles or components is used to manufacture an article or component of the article that at least partially comprises an ultraviolet (UV) curable material. The mold and apparatus comprise at least one mold wall formed of a cyclic olefin copolymer, which is in contact with UV radiation curable material and allows the article or component of the article to be exposed to UV radiation for a period of time in order to provide for at least partial cure thereof.
