In the late 1920s, during the great depression in the United States, the government issued a wonderful Law: prohibition. The prohibition lasted for 14 years, and wine bottle manufacturers were in trouble one after another. Owens Illinois company was the largest glass bottle manufacturer in the United States at that time. It could only watch glass furnaces turn off. At this time, a noble man, games slayer, happened to pass by a glass furnace and found that some spilled liquid glass was blown into fiber shape. Games seems like Newton was hit in the head by an apple, and glass fiber has been on the stage of history since then.
A year later, the Second World War broke out, and conventional materials were scarce. In order to meet the needs of military combat readiness, glass fiber became a substitute.
People gradually found that this young material has many advantages – light weight, high strength, good insulation, heat preservation and heat insulation. Therefore, tanks, aircraft, weapons, bulletproof vests and so on all use glass fiber.
Glass fiber is a new inorganic non-metallic material, which is made from natural minerals such as kaolin, pyrophyllite, quartz sand and limestone through several processes such as high-temperature melting, wire drawing and winding according to a certain formula. Its monofilament diameter is between several microns and more than 20 microns, which is equivalent to 1 / 20-1 / 5 of a hair filament. Each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments.
China’s glass fiber industry rose in 1958. After 60 years of development, before the reform and opening up, it mainly served national defense and military industry, and then turned to civil use, and achieved rapid development.
