Development of fiberglass

Fiberglass has a long history of development. In the 1930s, after Americans invented the process of using platinum crucibles to continuously draw glass fibers and blow glass wool with steam, the production of glass fibers formed a modern industry. With the development of modern science and technology, higher requirements have been placed on the mechanical and heat-resistant properties of glass fibers, which has led to the emergence of many special glass fibers since the 1960s, such as high-temperature-resistant glass fibers, high-strength glass fibers, and high-modulus glass fibers. Amount of fiberglass etc. The most eye-catching development process of high-performance glass fiber is the high-strength glass fiber "ZenTron" announced by Dow Corning for the first time at the 41st SAMPE International Conference in March 1996. It is made of high-silica content glass as raw material. Made of fibers using a technology called Single-busting or Single-end 30 type. This product requires fewer post-processing steps, can prevent fiber damage, and reduce costs.
Our country has a history of studying glass fiber for decades. As early as 1958, my country developed fiberglass boats using hand lay-up techniques, and developed fiberglass plates and rocket launchers using lamination and rolling techniques. In 1960, scientific research institutions were established in Beijing, Shanghai, and Harbin. In 1961, the ablation-resistant glass fiber end was successfully developed. In 1970, a 44m large glass radome was manufactured using hand-paste sandwich structural panels. In 1975, the FRP Society was established. In 1983, the China Building Materials Research Institute successfully trial-produced alkali-resistant glass fiber. Reinforced sulfate aluminate low-alkali cement composite materials. In 1988, Wuhan University of Technology successfully researched high-performance glass fiber-reinforced magnesium oxychloride composite materials. At present, both composite materials have reached industrial production scale and are widely used in construction projects.
