A method for bonding thermoplastic fiber-composite parts comprises providing surface texture on one or both parts being bonded, and/or providing both parts with engagement features. Such surface textures and engagement features have a specific geometry and fiber alignment that facilitate fibrous interlock between the two parts at a bonding interface via in-situ consolidation.

According to an aspect, a flow path component includes a flow path component body having a flow surface. The flow path component also includes a plurality of antimicrobial nanoparticles embedded in the flow surface and at least partially exposed external to the flow surface to provide an antimicrobial surface.

In-aircraft seats include plastic components having anti-microbial, metallic reinforcing fibers such as copper or silver. Copper or silver wires are embedded into the plastic at the time or molding to provide both structural reinforcement and anti-microbial properties. At the time of molding, copper or silver wires are disposed in a plastic mold prior to plastic application to ensure the metallic wires are generally disposed toward the surface of the molded part.

A preform-charge fixture creates a preform charge, which is a partially consolidated assemblage of preforms that can be efficiently transferred to a mold to create a finished part in a molding process, such as compression molding. In the illustrative embodiment, the preform-charge fixture includes peripheral cleats that are movable towards a central cleat to create a small gap therebetween that receives and constrains preforms in a desired position. The fixture also includes clamps, which are operable to engage an uppermost layer of preforms in the gap and apply a slight amount of downward pressure thereto to assure that the preforms are properly seated. The fixture also accommodates an energy source that heats the preforms so that, in conjunction with downforce applied by the clamps and/or gravity, the preforms can be tacked together, forming the preform charge.

In accordance with one embodiment, a metal part includes a geometric three-dimensional printed structure consisting essentially of pure metal. In accordance with another embodiment, a metallic precursor resin includes a metallopolymer material including a metal-thiolate polymer. The metallopolymer material is a metallogel. The metallogel is substantially transparent and has a viscosity for enabling three-dimensional printing thereof.

A composite fibrous susceptor for use in induction welding is described, along with methods of its construction and use. The composite fibrous susceptor can include a magnetically susceptible continuous fiber in conjunction with a thermoplastic polymer. The composite fibrous susceptor can be deposited according to an additive manufacturing process on a surface to be bonded according to an induction welding process.
