Plastic resin-impregnated three-dimensional hollow platelike woven fabric

Abstract

The invention discloses plastic resin-impregnated three-dimensional hollow platelike woven fabric. The structures of upper fabric and lower fabric are plain structures, wherein the upper fabric and the lower fabric are stripes which are separately arranged at intervals along the weft direction and are formed by strip-shaped non-woven fiber tapes; core yarns of a core material layer are staggered and intersected in an X-type matrix manner along the warp direction and are respectively interwoven, connected and supported with warps corresponding to the upper fabric and the lower fabric; the core yarns of the core material layer are continuously arranged in an up-and-down cut W form along the weft direction and are respectively interwoven, connected and supported with the warps corresponding to the upper fabric and the lower fabric; and the warps and wefts of the upper fabric and the lower fabric and the core yarns of the core material layer have main characteristics of a filament yarn pre-impregnated by thermoplastic resin. The plastic resin-impregnated three-dimensional hollow platelike woven fabric has the characteristics of being reasonable in structure, excellent in performance, convenient to mold and the like; and the required stuffing is convenient to fill.

Description

technical field [0001] The invention relates to a three-dimensional hollow plate-shaped woven fabric with plastic prepreg resin, specifically, the woven fabric is a three-dimensional hollow plate-shaped woven fabric, which can be ideally shaped by heating or hot pressing, and its hollow Part of the woven fabric can be filled with the required filling material according to the needs, which belongs to the technology of filling skeleton material for reinforcement of construction engineering and cold plastic industrial products. Background technique [0002] The traditional method of filling skeleton for building engineering reinforcement is to use wet layup or injection molding technology. This method undoubtedly has the disadvantages of large environmental pollution, waste of materials, long labor time, slow project progress and unstable project quality. Therefore, the industry generally expects to provide a three-dimensional hollow plate-shaped woven fabric prefabricated rein...

Problems solved by technology

[0004] However, the existing patented technology also has structural deficiencies: for example, the core yarn of the core material layer does not have an "X"-shaped simple orthogonal distribution structure in the weft direction, so that the warp and weft directions of the three-dimensional hollow woven fabrics The difference in mechanical properties is large. In order to ensure the quality of construction engineering, synthetic material products and glass fiber reinforced plastic products, the minimum value of the mechanical properties of the three-dimensional hollow woven fabric has to be adopted in the design, resulting in waste of the performance of the three-dimensional hollow woven fabric; and Since the core filaments (pillars) of the core material layer of the three-dimensional hollow woven fabric of the prior art are arranged in the shape of "1" in the warp direction, in the weaving process, the process of threading and closing the button will be unstable, etc. The problem is that the core column (yarn) is inverted along the weft direction, causing the upper and lower layers of woven fabrics to be displaced along the warp direction or along the weft direction after being stressed, which reduces the shear resistance of the three-dimensional hollow woven fabric and The stability of the overall structure negatively affects the quality of said architectural engineering products, synthetic material products and fiberglass products
