Glass fiber was invented in 1938 by an American company; During the Second World War in the 1940s, glass fiber reinforced composites were first used in military industry (tank parts, aircraft cabin, weapon shells, bulletproof vests, etc.); Later, with the continuous improvement of material performance, the decline of production cost and the development of downstream composite material technology, the application of glass fiber has been expanded to the civil field. Its downstream applications cover the fields of architecture, rail transit, petrochemical, automobile manufacturing, aerospace, wind power generation, electrical appliances, environmental engineering, marine engineering, etc., becoming a new generation of composite materials to replace traditional materials such as steel, wood, stone, etc, It is a national strategic emerging industry, which is of great significance to national economic development, transformation and upgrading.
From the perspective of the global market competition pattern, the annual glass fiber production capacity of the six major glass fiber manufacturers in China, Jushi, Taishan Glass Fiber, Chongqing International Composite, Owens Corning (OC), NEG and JM accounted for more than 75% of the total global glass fiber production capacity, and the annual glass fiber production capacity of the three major glass fiber manufacturers in China accounted for more than 70% of the domestic glass fiber production capacity. In terms of domestic output, the concentration of production in the glass fiber industry is high. In 2020, the proportion of CR3 and CR5 in the glass fiber industry will reach 72% and 83% respectively.
In addition to the three major glass fiber giants of China Jushi, Taishan Fiberglass and International Composite, there are outstanding glass fiber manufacturers in the industry, including Shandong Fiberglass, Sichuan Weibo, Zhengwei New Materials, Henan Guangyuan, Changhai Co., Ltd.
