The present disclosure provides systems and methods for producing composite materials. The methods may comprise feeding to an extruder one or more components which may comprise a first component comprising a fiber and a second component comprising a polymer-based matrix or composite to generate a composite material. The fiber may be a biological fiber in a rope form when being directed into the extruder.

A belt for suspending and/or driving an elevator car includes a plurality of cords. Each cord includes a plurality of wires and at least one yarn thread disposed at an outer periphery of the plurality of wires. An elastomeric jacket substantially retains the plurality of cords. The at least one yarn thread is configured to promote adhesion of the elastomeric jacket to the plurality of cords and reduce fretting of the plurality of wires. A method of forming a belt includes arranging a plurality of wires into a cord, arranging one or more yarn threads at an outer periphery of the plurality of wires, arranging a plurality of cords into a selected arrangement and applying an elastomeric jacket to the cords to retain the cords. The one or more yarn threads are configured to promote adhesion of the elastomeric jacket to the cords and reduce fretting of the wires.

An apparatus for forming a rope matrix having seaweed propagules embedded therein is provided and may include an intertwining assembly configured to intertwine at least three ropes at a braiding point to form a rope matrix. Further, the apparatus may include a conveying device configured to introduce seaweed propagules adjacent to the braiding point and to enable embedding of the seaweed propagules within the rope matrix while the rope matrix is being formed. Further, the apparatus may comprises an offtake assembly configured to move the rope matrix, with the seaweed propagules embedded therein, out of the apparatus.

A rope having a core for providing strength to the rope, where at least a metal or composite woven or warp knitted fabric having multiple substantially parallel elongated metal elements is provided around the core for protecting said core from impact and cutting, and where the multiple substantially parallel elongated elements are in the warp direction and held by yarns.

An article containing an innerduct structure and a woven rope located within the innerduct structure. The woven rope an inner portion comprising a plurality of multifilament fibers in the length direction of the woven rope and a jacket portion covering the inner portion. The jacket portion contains a plurality of monofilament fibers in the length direction of the woven rope and at least one multifilament fiber in the circumferential direction interwoven with the monofilament fibers in the length direction of the jacket portion. The monofilament fibers of the jacket portion form the majority of the outer surface of the woven rope.
