A method for forming a structural tile for use in a composite panel includes providing a base plate of a compression mold assembly. The method also includes placing a grid structure mold of the compression mold assembly atop the base plate. The grid structure mold defines a cavity having a desired shape for a grid structure. Further, the method includes filling the cavity of the grid structure mold with a plurality of fragments of recycled fiber reinforced polymer material. Moreover, the method includes placing a cover plate of the compression mold assembly atop the grid structure mold to apply pressure to the grid structure mold. The method also includes applying heat to the cover plate to heat the plurality of fragments of recycled fiber reinforced polymer material such that the recycled fiber reinforced polymer material melts within the cavity. In addition, the method includes allowing the melted recycled fiber reinforced polymer material to cure to form the structural tile.

A turbomachine blade is made of composite material formed of woven fibers and embedded in a polymerised resin. The blade includes a root connected by a stilt to a vane which comprises a pressure side and a suction side. At least one anti-wear strip of fabric is located on a surface of the root and/or the stilt. At least one anti-wear strip is secured to the root surface in a unitary manner by the resin.

An illustrative example embodiment of an elevator sheave assembly includes a plurality of polymer rings that are secured together. The plurality of polymer rings includes at least two polymer rings that each have an outer circumferential surface that defines a portion of a belt guiding surface adjacent a flange at a longitudinal end of the sheave assembly. The at least two polymer rings each include a bearing supported inside the ring.

A lacrosse head pocket and a related method of manufacture are provided to facilitate consistent, repeatable and/or custom manufacture of lacrosse equipment. The pocket can be constructed from multiple different sections joined with one another, or can be knitted, weaved or otherwise assembled on an automated assembly machine from strands, and/or can be formed as a unitary textile material having regions/sections with different physical and/or mechanical properties. The pocket can be integrally molded within portions of a lacrosse head to eliminate manually constructed connections between the pocket and lacrosse head. The lacrosse head can be integrally molded with a lacrosse handle to provide a one-piece unitary lacrosse stick. Related methods of manufacturing also are provided.

A composite structure and method of assembling a composite structure is provided. The composite structure includes a base member having an outer surface and an inner surface. The inner surface defines a channel therethrough. The composite structure further includes a support member coupled to the outer surface. A fabric overwrap is coupled to the support member.

A bilayer composite thin-film beam structure is described. The structure incorporates a bulk phase change material as small inclusions in one layer of a bimorph. The structure, also referred to as a phase change composite bimorph or PCBM, curls abruptly, and reversibly, at a phase transition temperature. Large curling and effective expansion coefficients are demonstrated. The PCBMs may be employed in various self-assembly mechanisms and actuators.

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.
