(1) Glass cloth The glass cloth produced in China is divided into two types: alkali-free and medium-alkali. Most of them are alkali-free glass cloth. Glass cloth is mainly used for the production of various kinds of electrical insulation laminates, printed circuit boards, various vehicle bodies, tanks, boats, molds and so on. Alkali glass cloth is mainly used for the production of plastic coated cloth, as well as for corrosion-resistant occasions. The characteristics of the fabric are determined by the fiber properties, the warp and weft density, the yarn structure and the weave. The warp and weft density is determined by the structure of the yarn and the texture. The latitude and longitude plus the yarn structure determines the physical properties of the fabric, such as weight, thickness and breaking strength. There are five basic textures: plain, twill, satin, rib and mat.
(2) Glass ribbons Glass ribbons are divided into woven and non-woven tapes (burrs). The main weave is plain weave. Glass ribbons are often used to make high-strength electrical components with good dielectric properties.
(3) Unidirectional fabric Unidirectional fabric is a four-striped satin or long-axis satin fabric woven from coarse warp yarns and fine weft yarns. It is characterized by high strength in the main direction of the warp.
(4) Three-Dimensional Fabrics Three-dimensional fabrics are relatively flat fabrics whose structural characteristics have evolved from one-dimensional, two-dimensional to three-dimensional, so that composite materials with this reinforcement have good integrity and profiling, greatly improving the composites. Interlaminar shear strength and damage tolerance of the material. It has developed with the special needs of the aerospace, aviation, weapons, and shipping sectors. Today its application has expanded to include automobiles, sports equipment, and medical devices. There are five main categories: woven three-dimensional fabrics, knitted three-dimensional fabrics, orthogonal and non-orthogonal non-woven three-dimensional fabrics, three-dimensional weaving fabrics and other forms of three-dimensional fabrics. The shape of the three-dimensional fabrics is block, columnar, tubular, hollow truncated cones and variable thickness profiled sections.
