A machine and method are presented for producing interlaced composite components. The method includes: depositing a first one or more warp filaments onto a deposition surface in a first linear direction, inserting, on top of the first one or more warp filaments, a first one or more weft filaments in a second linear direction, where the second direction is in the same plane as the first one or more warp filaments but is not parallel to the direction of the first one or more warp filaments, depositing, on top of the one or more first weft filaments, one or more second warp filaments in first linear direction, where the second one or more warp filaments are not collinear with the first one of more warp filaments, and inserting, on top of the second one or more warp filaments, a second one or more weft filaments in the second direction.

This rapier is for drawing-in a weft yarn into a shed of a weaving loom (2), along a drawing-in path. The rapier includes a rapier head (206) mounted at one end of the rapier, which extends along a main longitudinal is driven, along the drawing-in path, by a drive. Also included is a clamp (320) for catching a weft yarn, with the clamp being mounted in the rapier head, operable between an open and closed configuration. The rapier includes an electric motor, (208) mounted on the body for actuating the clamp and a mechanism (260-328) for transforming an output movement of the motor, which is a rotation around an axis (A208) parallel to the main longitudinal axis, into an opening or a closing movement of the clamp.

A guide device including a guide (1) with one or more guide elements (2) for guiding a rapier bar (3) in a rapier weaving machine, wherein this guide device is provided with an air circuit (5) through which compressed air can flow and which is provided with perforations (7) for cooling the rapier bar (3) by compressed air, and wherein this guide device is provided with a cooling circuit (8) through which coolant can flow for cooling the rapier bar (3) by coolant. In addition, an assembly of a rapier bar (3), drive (4) and such a guide device. Furthermore, a rapier weaving machine including such an assembly.

A machine for fabricating three-dimensional interlaced composite components including a frame, a deposition surface, a first set of two or more warp heads, a second set of two or more of warp heads, and a weft inserter. An interlaced composite component including a first set of two or more warp filaments parallel to each other and a first set of two or more weft filaments parallel to each other. Warp filaments are interlaced with, and bonded to, weft filaments. Warp filaments and weft filaments are interlaced in at least two different weave patterns. Warp filaments and weft filaments are continuous, and the weave patterns transition from one pattern to another.

Described herein is a reinforced polymer concrete composition that includes a polymer concrete cured while in contact with reinforcing material with a polymer that has a backbone containing cyclohexane dimethanol (CHDM). The polymer concrete can include an unsaturated polymer resin (UPR) as a binding agent. The reinforcing material and polymer concrete mixture can be brought in contact with each other prior to the polymer concrete curing. A cross-linking agent and a free radical initiator can be inserted for triggering a reaction between the CHDM-containing polymer and the UPR. The polymer can be a polyurethane or copolyester, such as polyethylene terephthalate glycol (PETG).
