The core raw material of glass fiber fabric is glass fiber, an inorganic non-metallic material primarily composed of silicon dioxide that is produced by melting and drawing at high temperatures. It combines excellent insulation, heat resistance, and corrosion resistance with high mechanical strength, though it is relatively brittle and has average abrasion resistance. Once woven into cloth, its properties are better suited to industrial applications, making it an indispensable base material in various fields such as composite materials and electrical insulation.
The performance of glass fiber fabric is determined by both its composition and structure. In terms of composition, it is primarily divided into three categories: alkali-free glass fiber cloth, which offers superior electrical insulation and mechanical properties and is primarily used in high-end applications; medium-alkali glass fiber cloth, which features outstanding acid resistance and cost-effectiveness, making it suitable for mid-range applications; and high-alkali glass fiber cloth, which, due to its limited performance, is mostly used in basic applications with lower requirements. In terms of structure and weave, plain weave fabric, with its balanced properties in all directions, serves as the core substrate for hand-laid fiberglass reinforced plastic (FRP); unidirectional fabric focuses on enhancing strength in a single direction, making it suitable for applications involving directional stress; and special weaves such as twill and satin can meet the personalized needs of different processing techniques, covering a wide range of production scenarios.
Glass fiber cloth significantly drives the upgrading of multiple core industries. First, as a reinforcing matrix for composite materials, it forms fiberglass when combined with resin to create a composite structure. Leveraging its lightweight, high-strength, and corrosion-resistant properties, it is widely used in the shipbuilding, automotive components, and building materials sectors, making it a key choice for lightweight materials; Second, as an electrical insulation material, it serves as the core substrate for printed circuit boards (PCBs) and is also used in the manufacture of motor insulation materials and high-voltage bushings. With the development of 5G and AI server industries, low-dielectric-constant electronic fabrics have become a key focus for the industry; Third, as a fire-resistant and thermal insulation material, it is widely used in fire curtains, high-temperature filtration materials, and protective clothing linings due to its non-flammable and high-temperature-resistant properties; Fourth, other industrial applications, including tile backings, pipeline corrosion-resistant materials, and conveyor belts.
Fine fiber dust generated during the processing of glass fiber fabric can be inhaled into the lungs; operators must wear professional dust masks at all times to prevent prolonged exposure. Broken glass fibers can irritate the skin; if contact occurs, rinse immediately with clean water without rubbing. Clothing that has come into contact with the fibers must be shaken out and washed separately to prevent fiber dispersion and secondary irritation.
By adjusting compositions, optimizing structures, and upgrading post-processing techniques, glass fiber fabric can continuously meet the evolving needs of industries such as high-end manufacturing, electronics and information technology, and safety protection.
