Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber cloth, in particular to a composite glass fiber cloth. Background Art

[0002] Fiberglass woven fabric is a plain weave fabric made of untwisted rovings and serves as an important base material for hand-layup fiberglass reinforced plastics (FRP). Woven fabric's strength lies primarily in the warp and weft directions. For applications requiring high strength in either the warp or weft direction, unidirectional fabric can also be woven, with a greater number of untwisted rovings arranged in either direction, resulting in single warp and single weft fabrics. Fiberglass is an inorganic, non-metallic material with excellent properties and is available in a wide variety of varieties. It is commonly used as a reinforcing material in composite materials, as an electrical and thermal insulation material, and as a circuit board in various sectors of the national economy.

[0003] The existing glass fiber cloth has poor overall tensile strength, which causes it to tear during use, thus shortening its service life. Utility Model Content

[0004] The purpose of the utility model is to provide a composite glass fiber cloth, which has the advantages of high overall structural strength and tensile resistance, and solves the problem that the current glass fiber cloth may be torn during use.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a composite glass fiber cloth, comprising a fiber cloth main body, the fiber cloth main body comprising a fiber layer, an upper glue layer is provided above the fiber layer, a lower glue layer is provided below the fiber layer, a wear-resistant covering layer is provided above the upper glue layer, a wear-resistant bottom layer is provided below the lower glue layer, and the fiber layer comprises a plurality of criss-crossed transverse reinforcing wires and longitudinal reinforcing wires.

[0006] Preferably, the fiber layer is formed by a plurality of transverse reinforcing filaments and longitudinal reinforcing filaments which are wavy and perpendicular to each other and reciprocally interlaced, and the transverse reinforcing filaments and longitudinal reinforcing filaments are both composed of composite fiber filaments.

[0007] Preferably, the composite fiber filaments are composed of a plurality of glass fiber filaments, and the plurality of glass fiber filaments are twisted into a twist shape.

[0008] Preferably, a square tensile-resistant cavity is formed between the plurality of transverse reinforcing wires and the longitudinal reinforcing wires.

[0009] Preferably, the spacing between the transverse reinforcing wires and the longitudinal reinforcing wires is between 50 μm and 150 μm.

[0010] Preferably, the upper glue filling layer and the lower glue filling layer are both filled into the fiber layer.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The utility model provides transverse reinforcing wires, longitudinal reinforcing wires, composite fiber wires, glass fiber wires and anti-tensile cavity. The fiber layer is composed of crisscrossing transverse reinforcing wires and longitudinal reinforcing wires, which can increase the overall tensile resistance of the glass fiber cloth. The anti-tensile cavity is provided for the upper and lower glue filling layers to be embedded, which can improve the overall structural strength of the glass fiber cloth.

[0013] 2. The utility model arranges composite fiber filaments and glass fiber filaments, and twists a number of glass fiber filaments to form a twist-shaped composite fiber filament, which can increase the diameter of the composite fiber filaments and increase the unevenness of the surface of the composite fiber filaments, so that the upper and lower glue layers are embedded in the interior after being applied, which can enhance the adhesion of the upper and lower glue layers and increase the overall structural strength of the glass fiber cloth.
