Abstract:
Described is a permeable multi-axial grid netting comprising a plurality of first and second threads (4, 5) which are interlaced and superposed to form a grid (2) whose meshes (3) present an irregular and/or regular closed broken line (6); each first and second thread (4, 5) comprises a plurality of strands (7) defined by thin, elongate elements placed side by side and joined to each other by impregnation with an adhesive resin (8).
Abstract:
The invention relates to a corrosion-resistant composite product which is obtained from composite strands which are formed by the drawing-phase mixing of filaments made from a thermoplastic material and filaments made from a mineral reinforcing material that is resistant to basic and/or acid corrosion, whereby at least part of the thermoplastic material is molten. The mineral reinforcing material comprises AR glass and the composite product is selected from at least one of the following products: a composite product obtained from the above-mentioned composite strands in the form of granules, a grid, a fabric, a multi-directional knit fabric, a braid, a continuous ribbon, a hollow body, a pultruded profile as a frame element, as a walkway, as a composite structural reinforcement, as nuts and bolts, a moulded product obtained by a mat of continuous composite strands in a molten thermoplastic material, a co-pultruded product obtained from strip(s) of fabrics of the composite strands and a bundle of said continuous composite strands. The invention also relates to the use of the composite product.
Abstract:
A non-woven mesh which can be used as a reinforcing frame, comprising superposed laps of longitudinal wires and cross-wires joined to each other by adhesive bonding and which define apertures enabling said mesh to be embedded inside the material which is to be reinforced, wherein wires (1a, 1b) (2) entering into the construction of said grid are composed of multifilament chemical wires whose mechanical characteristics are not impeded by the nature of the structure to be reinforced; in said mesh, the cross-wires(2) are imprisoned between two series of longitudinal wires (1a, 1b) which are superposed therebetween; the adhesive used to join the wires to each other surrounds said wires along the entire length thereof and links the pairs of longitudinal wires (1a, 1b) in areas (4) contained between two consecutive cross-wires (2), firmly maintaining said wires in relation to each other. The invention is characterized in that at least the cross-lap is composed of torsion-free multifilament wires, whereby the filaments thereof are disposed in a parallel, flat position forming a wide ribbon in relation to the thickness thereof.
Abstract:
A structural reinforcement in the form of an open gridwork which is advantageously used, for example, as part of a shoe sole. The structural reinforcement provides and/or enhances spring-like characteristics of the member it is reinforcing, propels and encourages the natural foot strike of the user to length the user's stride, increases the stride speed, and stabilizes the user's foot to prevent permanent compression of the midsole as a result of creep. The gridwork is impregnated throughout with a fully cured of B-stage thermosettable resin. The gridwork includes at least one continuous filament selected from the group consisting of glass, carbon, and aramid. The open gridwork is flat, corrugated, or double corrugated. The corrugated gridwork may be sinusoidal. The open gridwork may be part of a shoe midsole or may constitute a shoe midsole.
Abstract:
A reinforcing article (10, 100, 200) includes a porous substrate layer (105, 205) and a plurality of parallel first continuous fiber elements (12,114, 212) spaced apart from each other and extending along a first direction and fixed to the porous substrate (105, 205). Each first continuous fiber element (12,114, 212) includes a plurality of parallel and co-extending continuous fibers (22, 122, 222) embedded in a thermoplastic resin (24, 124, 224).
Abstract:
A method of forming a fibre reinforced polymer structure, comprises the steps of :- providing a first bundle of fibres arranged in an array and having a first fibre volume fraction (FVF); forming a node region in the bundle wherein a transverse dimension of the first bundle is increased and a second perpendicular dimension of the bundle is decreased so that the first FVF is maintained at an approximately constant value; providing a second bundle of fibres extending in angular relation to the first bundle, arranged in an array and having a second FVF; forming a node region in the second bundle wherein a transverse dimension of the second bundle is increased and a perpendicular dimension of the second bundle is decreased so that the second FVF is maintained at an approximately constant value; wherein the node region of the second bundle overlies the node region of the first bundle to form an assembly; wherein the second bundle extends from a single side of the first bundle; infusing the assembly with a polymer resin; and curing the resin to form the structure.
Abstract:
The invention is directed to fiberglass reinforced plastic panels (10) having increased tear resistance. Increased tear resistance is provided by an open-weave scrim (20) which is incorporated into the panel. The panels are useful in the manufacture of truck bodies and trailer roofs.
Abstract:
The present invention relates to elastic laminate structures comprising an open cell polymeric mesh (36) integrally thermal bonded between two fabric carrier layers (37, 38) and methods for manufacturing such laminates.
Abstract:
A fabric meshed reinforced monolithic thermoplastic membrane (44) comprising an open mesh fabric (46) and a thermoplastic layer (48), the thermoplastic layer (48) having been extruded separately and simultaneously in a molten state onto both sides of the open mesh fabric (46) wherein the extruded molten thermoplastic enters into and passes through the open mesh of the fabric mesh to form the monolithic thermoplastic membrane (44).
Abstract:
The support ensures the flow of the lacto-serum of the cheese during the acidification phase, preventing subsequent fungus development. It also enables circulation of brine on the upper surface of the cheese and ensures optimum ventilaiton of the lower surface during refining and storage. The support consists of a mesh (27) consisting of warp and weft threads. The assembly is impregnated with an anti-corrosion resin.
