In recent years, the development of application fields that have been relatively active internationally includes the following aspects:
(1) Fiberglass knitted fabric. In order to meet the reinforcement effect of fiberglass in composite materials such as wind turbine blades, ships, and sports equipment, fiberglass knitted fabrics have developed rapidly. Fiberglass yarn lining in the fabric is in a straight (non separating) state and has more directionality (including uniaxial, biaxial, and multiaxial fabrics). The development of three-dimensional reinforcement substrates for needles, machines, and weaving is also rapidly underway, especially for hollow core board reinforcement substrates, which are more popular.
(2) Reinforced thermoplastic. Almost all fiberglass enterprises are dedicated to meeting this demand.
â‘  In terms of short cut glass fiber powder: In traditional injection molded FRTP products, specialized glass fiber short cut products are produced for different reinforcement objects, and new series are continuously introduced to achieve high performance.
â‘¡ In terms of continuous glass fiber powder: GMT component products are also being promoted. In order to further improve the performance of FRTP products, glass fiber and engineering plastic enterprises are actively cooperating to develop continuous glass fiber powder reinforced thermoplastic substrates. Development of pre mixed and pre stained products, including mixed yarns of fiberglass and plastic.
As a glass fiber powder in the materials industry, how to better utilize its own characteristics and continuously expand its application fields is a permanent topic. The key technical link is to solve the coupling between glass fiber powder and the reinforced matrix to achieve the best composite effect.
Fiberglass insulation, thermal insulation and insulation materials:
Glass fiber is commonly used as a reinforcing material in composite materials, electrical insulation materials, insulation materials, circuit substrates, and other fields of the national economy. It is an excellent inorganic non-metallic material with a wide variety of types. Its advantages are good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, but its disadvantages are brittleness and poor wear resistance. Glass fibers can be divided into continuous fibers, fixed length fibers, and glass wool according to their shape and length; According to the composition of glass, it can be divided into alkali free, chemical resistant, high alkali, medium alkali, high strength, high elastic modulus, and alkali resistant glass fibers.
Short cut glass fiber is made from glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its single filament ranges from a few micrometers to over twenty meters, which is equivalent to 1/20-1/5 of a single strand of hair. Each bundle of fiber precursor is composed of hundreds or even thousands of single filaments. Glass fiber has higher temperature resistance, non flammability, corrosion resistance, good insulation and sound insulation, high tensile strength, and good electrical insulation than organic fiber. But it is brittle and has poor wear resistance. Industrial filtering materials, anti-corrosion, moisture-proof, thermal insulation, soundproofing, and shock-absorbing materials. It can also be used as a reinforcing material to manufacture reinforced plastics or rubber. As a reinforcing material, glass fiber has the following characteristics, which make its use far more extensive than other types of fibers, and its development speed is also far ahead.
