Method for producing a part made of composite material, and so obtained composite part
A method for producing a part made of composite material includes adding a thermoplastic or thermosetting matrix around a preform of a reinforcing fiber mesh made by filament winding around the spurs or the like of a frame. There is winding in addition to the fibers on one or several reels within the matrix, the axes of the spurs or the like and those of the one or more reels having different orientations, so as to provide the mesh of fibers with a three-dimensional shape.

A vehicle interior part includes a substrate, a first outer layer, a second outer layer, an upper reinforcement layer, a lower reinforcement layer, and a bottom fabric layer, where a first surface and a second surface of the substrate are bonded to a first surface of the upper reinforcement layer and a first surface of the lower reinforcement layer, respectively, a second surface of the upper reinforcement layer is bonded to a first surface of the first outer layer, a second surface of the first outer layer is bonded to the second outer layer, and a second surface of the lower reinforcement layer is bonded to the bottom fabric layer.
Bearing, traction or drive element made of an elastomer material having embedded electronic components
A band or belt designed as an elongate bearing, traction or drive element running around rollers or pulleys and made of an elastomer material, and preferably provided with embedded reinforcing elements or tension members extending in the longitudinal direction of the band or belt, having the following features: the band or the belt has one or more elongate tubular receptacles embedded in the elastomer material, in the cavity of which electronic components are arranged, preferably sensors, signal processing or control devices and/or transmission devices, the tubular receptacles are embedded in the elastomer material in such a way that their longitudinal axis or the direction of their greatest extent is oriented substantially transversely to the main bending direction of the band or belt.
Forming systems and methods for drape forming a composite charge
Forming systems and methods for drape forming a composite charge are disclosed herein. The forming systems include a forming die having a forming surface configured to receive the composite charge and a collapsible support having a support surface. The forming surface has a forming surface edge that extends along a length of the forming surface, and the support surface has a die-proximate support surface edge that extends along the length of the support surface. The forming surface edge and the die-proximate support surface edge define a gap therebetween. A shape of the die-proximate support surface edge corresponds to a shape of the forming surface edge such that a gap width of the gap is at least substantially constant along a length of the gap. The collapsible support is configured to transition from an extended conformation to a collapsed conformation. The methods include methods of utilizing the systems.
Undergarment receiving a thin intermediate bonding layer between two textiles prior to thermoforming
A process for manufacturing an undergarment having two superimposed textiles, comprising depositing on certain parts of reinforcements (8) comprising a thick layer of a shaped memory foam elastic material, the polymerization of this material and also the shaping of the textiles of the undergarment by thermoforming, characterized in that it comprises a step of depositing, on the entire surface of at least the textiles, a thin layer of an elastic adhesive-bonding material, and then a step of polymerizing this thin layer of adhesive bonding during the thermoforming for shaping, and in that it comprises a step of prior depositing, on the textile receiving the layer of reinforcement (8), of a barrier layer of an elastic material, which is polymerized before the depositing of this reinforcement.
Method for manufacturing fiber-reinforced plastic
A method for producing a fiber reinforced plastic can suppress with which wrinkling or bridging in a convex surface or a concave surface having a large curvature at the same time even if the fiber reinforced plastic has a complicated three-dimensional shape. Such methods for producing a fiber reinforced plastic may involve shaping a prepreg sheet in which continuous fibers are impregnated with a resin material into a three-dimensional shape to produce a fiber reinforced plastic (a); wherein at least a portion of the continuous fibers in an area (X) of the prepreg sheet corresponding to an area (X′) in which the fiber reinforced plastic (a) is shear-deformed is bent in an in-plane direction in advance.
IMPACT RESISTANT GARMENT
An impact resistant textile-supported garment, or component thereof, comprises a fabric layer, and (i) at least five non-interconnected impact resistant polyurethane segments upon an outer surface of the fabric layer, wherein at least two of the non-interconnected impact resistant polyurethane segments has a depth of at least 3 mm, preferably at least 4 mm, and wherein at least five of the plurality of non-interconnected segments have dimensions smaller than 1.75 cm × 1 cm × 1 cm; or (ii) at least one non-interconnected impact resistant polyurethane segment, wherein the at least one segment has a depth of at least 3 mm at its deepest part, and wherein the at least one segment is a hollow segment comprising one or more regions defined by an outer polyurethane perimeter, surrounding a region of fabric that is not covered by polyurethane.
SECONDARY CUSHIONING ELEMENTS FOR CUSHIONS
A cover for a cushion includes a first panel, a second panel, and a primary receptacle defined between the first panel and the second panel. The primary receptacle may receive a primary cushioning element, such as a pillow, a pillow insert, or a fill material. At least one of the first panel and the second panel includes a secondary cushioning element. The secondary cushioning element may be defined from a compressible, resilient elastomeric material that defines a plurality of thin interconnected walls that in turn define an array of open cells or columns. Each cell or column may have a hexagonal shape, imparting the array of open cells or columns with a honeycomb appearance. Methods for assembling a primary cushioning element with such a cover are also disclosed.
Process For Manufacturing A Conveyor Belt
Methods of manufacturing a conveyor belt (126) include applying a rubber composition (114) to a first side of fabric reinforcement (112) and scattering productive thermoplastic elastomer pellets (106) onto a second side of the fabric reinforcement to produce an uncured belt structure (120). The uncured belt structure (120) is continuous fed into a double belt press (116) to press the productive thermoplastic elastomer pellets (106) together with the fabric reinforcement (112) to produce an uncured belt (128). Uncured belt (128) is then heated in the double belt press (116) to a temperature of at least 300° F. and maintained in the double belt press (116) under a pressure of at least 12 psi and a temperature of at least 300° C. for a residence time of at least 20 minutes to produce a cured conveyor belt (130), which is continuously withdrawn from the double belt press (116).
