Glass fibers are thin strands made from molten glass that are drawn into fine filaments. They are known for their strength, lightweight nature, and resistance to heat and chemicals. These properties make glass fibers ideal for use in various applications, including construction, automotive, and aerospace industries. In addition to their structural uses, glass fibers are often combined with resins to create composite materials. These composites are used in products like boats, sports equipment, and insulation. The versatility and durability of glass fibers contribute to their popularity in both industrial and consumer products.
