Fiberglass, also known as fibreglass, is a type of fiber-reinforced plastic made from glass fibers. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. Fiberglass is composed of a combination of resin and glass fibers, which creates a fiber-reinforced plastic. Different resins can be added to make the product stronger, tougher, and less brittle. The basic raw materials for fiberglass products are a variety of natural minerals and manufactured chemicals, including silica sand, limestone, and soda ash, among others. Fiberglass is widely used in a variety of applications, including insulation, building materials, boats, aircraft, and sports equipment. It is a highly versatile lightweight material that is often used as a durable and cost-effective alternative to concrete, wood, and metal. Fiberglass is known for its strength, durability, and flexibility, and it can be molded into many complex shapes, making it an excellent construction material.
