sợi thủy tinh
The term "glass fiber" originated in the early 20th century, as a result of scientific discoveries related to glass melting and fiber spinning techniques. In 1932, Dr. Dale Kent Evans, a chemist at Owens-Illinois Glass Company, devised a method to make glass fibers from melted glass. The process involved blowing air into the molten glass stream and spinning it into fibers. Initially, the application of glass fibers was limited to reinforcing plastics and insulating electrical wires. In 1935, DuPont introduced fiberglass insulation, which quickly gained popularity, primarily due to its high insulation value and resistance to chemical and fire damage. Over the years, glass fibers have found applications in a wide range of industries, such as construction, automotive manufacturing, aerospace, and medical technology. The high-tech manufacturing process, known as melt spinning, involves melting pure silica at extremely high temperatures, followed by the addition of boron oxide and other chemicals to improve its strength, flexibility, and durability. In summary, "glass fiber" is a synthetic material created through the melting and spinning of glass, discovered by Dr. Dale Kent Evans in the 1930s, and used extensively in various industries due to its unique properties.
