In recent years, the FRP are widely used in the following areas:
(1) Glass fiber knitted mat. In order to meet the reinforcing effect of glass fiber in composite materials such as wind turbine blades, ships and sports equipment, glass fiber knitted fabrics are rapidly developed, and the glass fiber roving lining is straight (no precipitation), has more directionality (Includes uniaxial, biaxial and multiaxial fabrics). Three-dimensional reinforcement materials are also rapidly being developed, and air core panels in particular popular.
(2) Reinforced thermoplastics. Almost all fiberglass companies are eager to meet this demand.
1 Short-cut glass fiber powder: In the traditional injection molding FRTP products, we specialize in the production of chopped glass fiber for enhanced objects, and continuously introduce new series to achieve high performance.
2 Continuous glass fiber powder: GMT component products are also being promoted. In order to improve the performance of FRTP products, glass fiber and engineering plastics companies are actively developing a continuous glass fiber powder reinforced thermoplastic substrate. Premixed, pre-stained product development, including mix glass fiber roving and plastic.
As a glass fiber powder in the material industry, how to better use its own characteristics and continuously expand the application field is a permanent topic. The key technical link is to solve the coupling of glass fiberglass powder and the reinforced matrix to obtain the best compound. effect.
Glass fiber insulation material:
Glass fiber is generally used as a reinforcing material in composite materials, electrical insulating materials and thermal insulation materials, circuit boards and other fields of the national economy. It is an inorganic non-metallic material with excellent performance. It has many advantages, such as good insulation and heat resistance. Strong in nature, good in corrosion resistance and high in mechanical strength, but the disadvantage is that it is brittle and wear resistance is poor. Glass fiber can be divided into continuous fiber, fixed length fiber and glass wool according to shape and length. According to glass composition, it can be divided into alkali-free, chemical-resistant, high alkali, medium alkali, high strength, high elastic modulus and alkali-resistant glass. Fiber, etc.
Glass fiber chopped strands are made by glass ball or waste glass by high-temperature melting, drawing, winding, weaving, etc., and the diameter of the monofilament is several micrometers to twenty meters micrometers, each bundle of fiber strands consists of hundreds or even thousands of monofilaments. Glass fiber is more resistant to temperature than organic fiber, non-combustible, anti-corrosion, heat insulation, sound insulation, high tensile strength and good electrical insulation. However, it is brittle and has poor abrasion resistance. Industrial filter materials, anti-corrosion, moisture-proof, heat-insulating, sound-proof, shock-absorbing materials. It can also be used as a reinforcing material to make reinforced plastics or reinforced rubber. As a reinforcing material, glass fiber has the following characteristics. These characteristics make the use of glass fiber far wider than other kinds of fibers, and the development speed is far ahead.
