Glass fiber cloth

The following are various glass fiber fabrics woven from glass fiber yarn, including glass fiber fabrics.

(1) Glass cloth: The glass cloth produced in China is divided into two categories: alkali free and medium alkali free, and most of them are E-GLASS alkali free glass cloth in foreign countries. Glass cloth is mainly used for producing various electrical insulation laminates, printed circuit boards, various vehicle bodies, storage tanks, boats, molds, etc. Medium alkali glass cloth is mainly used for producing plastic coated packaging cloth and for corrosion-resistant occasions. The characteristics of a fabric are determined by fiber properties, warp and weft density, yarn structure, and texture. The density of warp and weft is determined by the yarn structure and weave pattern. The close combination of warp and weft and yarn structure determines the physical properties of the fabric, such as weight, thickness, and breaking strength. There are five basic weaves: plain weave plan (similar to checkered fabric), twill weave (usually+-45 degrees), satin statin (similar to unidirectional fabric), rib leno (the main weaving method of fiberglass mesh fabric), and mat mats (similar to Oxford fabric).

(2) Glass fiber tapes are divided into woven edge bands (smooth edge bands) and non woven edge bands (rough edge bands). The main weaving method is plain weave. Alkali free fiberglass tape is commonly used to manufacture electrical equipment components with high strength and good dielectric properties.

(3) Glass fiber unidirectional fabric, among which single warp fabric is a four warp broken satin or long axis satin fabric woven from coarse warp and fine weft yarns, characterized by high strength at 0 degrees in the main warp direction. There are also glass fiber single weft fabrics, with two weaving methods: warp knitting and machine weaving. The characteristic is that coarse weft yarn, fine warp yarn, and glass fiber yarn are fed in the weft direction, and have high strength in the 90 degree weft direction.

(4) Glass fiber three-dimensional fabric The three-dimensional fabric is relative to the plane fabric, its structural characteristics have developed from one-dimensional and two-dimensional to three-dimensional, so that the composite with this as the reinforcement has good integrity and profiling, greatly improving the interlaminar Shear strength and Damage tolerance of the composite. It has developed with the special needs of sectors such as aerospace, aviation, weapons, and shipbuilding, and its applications have now expanded to sectors such as automobiles, sports equipment, and medical equipment. There are mainly five types: woven three-dimensional fabrics, knitted three-dimensional fabrics, orthogonal and non orthogonal non-woven three-dimensional fabrics, three-dimensional woven fabrics, and other forms of three-dimensional fabrics. The shapes of three-dimensional fabrics include block, column, tube, hollow truncated cone, and variable thickness irregular cross-section.

(5) The shape of glass fiber shaped fabric is very similar to the shape of the product it is intended to enhance, and must be woven on a dedicated loom. Asymmetric shaped fabrics include round covers, cones, hats, dumbbell shaped fabrics, and can also be made into asymmetric shapes such as boxes and ship shells.

(6) Glass fiber slot core fabric is a fabric composed of two parallel layers of fabric connected by longitudinal vertical bars. Its cross-sectional shape can be triangular, rectangular, or honeycomb structure.

(7) Glass fiber woven fabric, also known as knitted felt or woven felt, is different from both ordinary fabrics and ordinary felt. The most typical knitted fabric is a layer of warp and weft yarns that overlap and are woven together through sewing to form a fabric. The advantages of seam woven fabric are as follows: ① It can increase the ultimate tensile strength, delamination strength under tension and Flexural strength of FRP laminated products; ② Reduce the weight of fiberglass products; ③ Smooth surface to make the fiberglass surface smooth; ④ Simplify hand layup operations and improve labor productivity. This reinforcing material can replace continuous strand felt in pultrusion fiberglass and RTM, and can also replace square cloth in centrifugal fiberglass production.
