Glass fiber has excellent performance and many application scenarios: Glass fiber is an inorganic non-metallic composite fiber material with excellent performance, which has a series of advantages such as low cost, light weight, high strength, high temperature resistance and corrosion resistance. Its specific strength reaches 833Mpa/gcm3, second only to fibra de carbono
(over 1,800Mpa/gcm3) among common materials. Due to the mature mass production technology, low cost, numerous sub-categories, and comprehensive cost-effectiveness of fiberglass premium
, different products can be designed according to different scenarios, so it is widely used in various scenarios and is the most important inorganic non-metallic composite material today. one.
There are many classification methods and types of glass fiber: the glass fiber industry is divided into three parts: glass fiber yarn, glass fiber products, and glass fiber composite materials, each of which has a variety of varieties. Among them, glass fiber yarn has many classification methods. According to the oxide content, it can be divided into alkali-free yarn, medium alkali yarn, etc.; according to diameter, it can be divided into glass fiber rovings
, finre glass yarn
, etc.; according to length, it can be divided into continuous glass fiber, fixed-length Glass fiber, fiberglass scrap
, etc.; According to the product form, it is divided into twisted yarn and untwisted yarn, and can also be woven into fiberglass mat cloth
. In some applications, the untwisted roving is further chopped to make Glass fiber strands
The glass fiber industry involves many upstream and downstream, and is divided into three links: glass fiber yarn, glass fiber products, and glass fiber composite materials: the glass fiber industry chain is long, and the upstream mainly involves basic industries such as mining, chemical industry, and energy. The downstream of glass fiber is various application industries, including building materials, electronic appliances, wind power generation, industrial pipe tanks, aerospace and military industries. At present, the downstream application field of glass fiber is still expanding, and the industry ceiling is still gradually improving.
