A composite is a material that is made of two or more different materials. In the case of fiberglass, the two materials are glass fibers and a polymer resin. The glass fibers are what give the composite its strength, while the polymer resin holds the fibers together and protects them from damage.
Fiberglass is a very versatile material that can be used in a wide variety of applications, from construction to automotive parts to sporting goods. It is strong, lightweight, and resistant to corrosion, making it an ideal choice for many different projects.
