(1) Glass cloth The glass cloth produced in China is divided into two types: alkali-free and medium-alkali. Most foreign countries are alkali-free glass cloth. Glass cloth is mainly used to produce various electrical insulating laminates, printed circuit boards, various vehicle bodies, storage tanks, boats, molds, and the like. Medium alkali glass cloth is mainly used for the production of coated packaging fabrics and for corrosion resistant applications. The properties of the fabric are determined by fiber properties, warp and weft density, yarn structure and texture. The warp and weft density is determined by the yarn structure and texture. The warp and weft density 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 ribbon The glass ribbon is divided into a woven side belt and a non-woven side belt (burr belt). The main weave is plain weave. Glass ribbons are often used to make high-strength, dielectric-good electrical equipment components.
(3) Unidirectional fabric The unidirectional fabric is a four-striped or long-satin satin fabric woven from coarse warp yarns and fine weft yarns. It is characterized by high strength in the warp main direction.
(4) Three-dimensional fabric three-dimensional fabric is a relatively flat fabric, and its structural features have evolved from one-dimensional two-dimensional to three-dimensional, so that the composite material with the reinforcement has good integrity and profiling, greatly improving the composite. Interlaminar shear strength and damage tolerance of the material. It has been developed with the special needs of aerospace, aviation, weapons, ships and other departments. Today its application has been extended to the automotive, sports equipment, medical equipment and other departments. There are five main categories: woven three-dimensional fabrics, knitted three-dimensional fabrics, orthogonal and non-orthogonal nonwoven three-dimensional fabrics, three-dimensional woven fabrics, and other forms of three-dimensional fabrics. The shape of the three-dimensional fabric has a block shape, a column shape, a tubular shape, a hollow truncated cone shape, and a variable thickness profile cross section.
