A vehicle seating system may include a seat part having a trim material positioned over a base material. A method for producing the seating system may include configuring an attachment arrangement to have an adhesive material and a non-adhesive material bonded to the adhesive material. The method may also include molding the base material onto the non-adhesive material such that a surface of the adhesive material faces outward away from the base material. The trim material may be disposed over the base material such that a back side of the trim material is adhered to the adhesive material.

An overmolded thermoplastic article includes a substrate portion molded from a thermoplastic resin compound and an overmold portion molded from a thermoplastic elastomer compound. The thermoplastic resin compound includes thermoplastic polymer resin. The thermoplastic elastomer compound includes thermoplastic elastomer and polysiloxane as a mold release agent, and is free of wax. The overmold portion is bonded onto the substrate portion with a peel strength at least comparable to that of an overmolded thermoplastic elastomer compound containing wax as a mold release agent instead of the polysiloxane. Undesirable effects observed with the use of wax as a mold release agent in overmolded thermoplastic elastomer compounds such as blooming and ease of scratching/marring can be reduced, while desirable properties such as silky feel of the surface of the overmold portion and good bonding of the overmold portion onto the substrate portion can be at least maintained.

A reinforcing article includes a porous substrate layer separating a plurality of parallel first continuous fiber elements spaced apart from each other and extending along a first direction from a plurality of parallel second continuous fiber elements spaced apart from each other and extending along a different direction. Each first and second continuous fiber elements include a plurality of parallel and co-extending continuous fibers embedded in a thermoplastic resin.

A system for additively manufacturing a composite structure is disclosed. The system may include a print head configured to discharge a matrix-coated reinforcement, and a support configured to move the print head in multiple dimensions during discharging of the matrix-coated reinforcement. The system may further include at least one cure enhancer located offboard the print head, and a controller in communication with the support and the at least one cure enhancer. The controller may be configured to selectively activate the at least one cure enhancer to expose the matrix-coated reinforcement to a cure energy during discharging of the matrix-coated reinforcement.

Hollow composite dowel bar assemblies, their manufacture, and apparatus for manufacture. The dowel bar assemblies may include an elongate and hollow core, a protective jacket coating at least the sidewall exterior of the core, and a sealing structure coupled with each end of the combined core and jacket, that are configured to protect the core from the environment.

There is disclosed a method of manufacturing a fan blade for a gas turbine engine, the method comprising: providing a root insert comprising quasi-isotropic short fibre reinforced resin, providing a first sub-laminate of a fibre-reinforcement pre-form for the fan blade on a first mould surface, placing the root insert on the first sub-laminate at a position corresponding to a root of the fan blade, providing a second sub-laminate of the pre-form over the root insert and the first-sub-laminate, so that the root insert is at an intermediate position between the first and second sub-laminates; and applying heat and pressure to form the pre-form.

A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (is) at least one consolidated fibrous insert having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier will be a mass of activatable material.

An apparatus for securing first and second skins to a core in a composite rotor blade includes an elongated member configured to be installed through a passage in the core of the composite rotor blade. The elongated member has a first end configured to be attached to an outer surface of the first skin and a second end configured to be attached to an outer surface of the second skin. The apparatus also includes a first patch configured to adhere the first end to the outer surface of the first skin, and a second patch configured to adhere the second end to the outer surface of the second skin such the elongated member extends from the outer surfaces of the first and second skins through the passage in the core.
