Glass fiber, also known as fiberglass, is a synthetic material composed of fine strands of glass. It is made by extruding molten glass through tiny openings to create thin fibers, which are then woven together or used as reinforcing agents in various materials. Glass fiber is valued for its strength, durability, and versatility, making it a popular choice in a wide range of applications. It is commonly used in industries such as construction, automotive, aerospace, and marine, where its lightweight yet robust properties are beneficial. Glass fiber is known for its resistance to corrosion, heat, and electrical conductivity, making it suitable for diverse uses including insulation, reinforcement, and composite materials.
