In depth report on glass fiber industry: it is a cyclical industry with growth and is optimistic about the continued prosperity of the industry

Glass fiber has excellent performance and many application scenarios. Glass fiber is an inorganic non-metallic composite fiber material with excellent properties. It has a series of advantages, such as low cost, light weight, high strength, high temperature and corrosion resistance. Its specific strength reaches 833mpa / gcm3, which is second only to carbon fiber (more than 1800mpa / gcm3) in common materials. Due to the mature mass production technology of glass fiber, low cost, low unit price, many subdivided categories, the comprehensive cost performance is obviously better than carbon fiber, and different products can be designed according to different scenes. Therefore, glass fiber is widely used in various scenes. It is one of the most important inorganic non-metallic composites today.
The glass fiber industry involves many upstream and downstream, which 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 is mainly designed for mining, chemical industry, energy and other basic industries. From top to bottom, the glass fiber industry is divided into three links: glass fiber yarn, glass fiber products and glass fiber composites. The downstream of glass fiber is various application industries, including building materials, electronics and appliances, wind power generation, process pipe and tank, aerospace and military industry. At present, the downstream application field of glass fiber is still expanding, and the industry ceiling is still gradually improving.
China’s glass fiber industry has experienced more than 60 years of development, which is divided into four stages: the description of the development of glass fiber industry. China’s glass fiber industry has experienced more than 60 years of development since the annual output of 500t of Shanghai Yaohua Glass factory in 1958. It has experienced the process from scratch, from small to large, from weak to strong. At present, the production capacity, technology and product structure are at the world leading level. The development of the industry can be roughly summarized into four stages. Before 2000, China’s glass fiber industry mainly used crucible production method with small output, which was mainly used in the field of national defense and military industry. Since 2001, tank kiln technology has been rapidly popularized in China, and the domestic output has increased rapidly. However, the output of low-end products is mainly dependent on export. In 2008, affected by the financial crisis, the scale of the global market shrank, and China’s glass fiber industry overtaked at the curve, becoming the largest country in the world. After 2014, China’s glass fiber industry opened an era of upgrading, gradually entered a period of high-quality development, gradually reduced its dependence on overseas markets and significantly increased its influence in the international market.
