Glass Fibers
Glass fibers are widely utilized as reinforcements in composite materials, offering a balance of strength, affordability, and corrosion resistance. Composed primarily of silica and other materials, glass fibers come in various forms, such as continuous strands or woven mats. They are adept at reinforcing composites, providing excellent tensile strength while being relatively lightweight.
