Disclosed herein are systems and techniques for producing complex components using a reinforced thermoplastic material. The complex components can include contoured or curved outer surfaces, and in some cases define a cavity. In certain examples, one or more thermoplastic materials are arranged to form a wheel component, such as that adapted to define a rim of the bicycle. Thermal bonding can be used to join multiple reinforced thermoplastic materials to one another in order to form a cavity of the wheel component or other complex shape. In certain examples, a portion of a tooling assembly can be pressurized to maintain a shape of the cavity during thermal bonding and cooling. This can remove the need for a sacrificial bladder or other structure that would maintain the shape of the cavity, allowing for a seamless final component, optionally absent indicia of bladder exit or other seams.

Methods of manufacture for reinforced thermoplastic components

Reinforced thermoplastic components and method of manufacture thereof

A composite ammunition magazine comprises a box with a follower slidably disposed in the box and a spring disposed between a bottom of the box and the follower and biasing the follower towards an open top. A pair of opposite lips extends from proximal ends at opposite sides of the open top in an arc to distal free ends over the open top of the box. The box and the pair of lips comprise a composite material comprising fibers in a resin matrix with the sides of the box comprising hoop fibers oriented at 0 degrees and axial fibers oriented at 90 degrees, and the pair of lips comprising lateral fibers oriented at 0 degrees and arc fibers extending in an arc and oriented at 90 degrees with respect to the lateral fibers. The pair of lips comprises more arc fibers than the axial fibers in the box.

A trigger assembly for use with a firearm has a hook carried by and pivotal with a selector to engage an aft tab of a hammer in the safe position of the selector.

A rifle barrel for a gas-operated rifle includes a metallic liner with a longitudinal bore and a transverse gas port through the liner to the bore intermediate along a length of the liner. A thermally conductive sleeve circumscribes the liner substantially along the length of the liner. A composite wrap circumscribes the sleeve substantially along a length of the sleeve. The composite wrap is separated from the gas port.

An integral hand guard and accessory rail has an elongated shell with a shell wall adapted to be spaced-apart from and circumscribing a barrel of a firearm. The shell has a portion adapted to be griped by a user and defining a hand guard. The shell wall has another portion protruding radially away from the barrel defining an elongated rail, the rail having a cross-sectional shape orthogonal to the axis with a narrower neck a wider head coupled to the shell by the neck.

According to one embodiment, a bow includes a handle portion and a bowstring. Compression members including primary compression elements and secondary compression elements are positioned on the ends of the handle portion. The compression elements are arcuate in shape and joined at the ends. As the bowstring is drawn, the compression members are compressed and energy is stored therein. The bow can include limbs that do not significantly deform or store energy as the bow is drawn. Upon release of the bowstring, the stored energy is rapidly returned to the bowstring.

An architectural column includes a tubular column body having a longitudinal axis extending from a first end to a second end, at least one inner layer, at least one support layer and at least one outer layer, wherein the support layer includes a composite fabric having fibers and a bonding resin.
