Fiberglass is actually made from glass similar to that used in windows or kitchen drinking glasses. Its manufacturing process involves heating the glass to a molten state, then forcing it through an ultra-fine orifice to form extremely thin glass filaments. These filaments are so fine they can be measured in micrometers.
These soft, fine filaments serve multiple purposes: they can be woven into larger materials for creating fluffy-textured insulation or soundproofing; or they can be retained in a less structured form for manufacturing various automotive exterior parts, swimming pools, spas, doors, surfboards, sports equipment, and hulls. For certain applications, reducing impurities in the fiberglass is crucial, requiring additional steps during production.
Once woven together, glass fibers can be combined with different resins to enhance product strength and molded into diverse shapes. Their lightweight yet durable properties make glass fibers ideal for precision applications like circuit boards. Mass production occurs in the form of mats or sheets.
For items like roof tiles, large blocks of fiberglass and resin mixture can be manufactured and then cut by machine. Fiberglass also features numerous custom application designs tailored to specific uses. For instance, automotive bumpers and fenders sometimes require custom fabrication—either to replace damaged parts on existing vehicles or during the production of new prototype models. The first step in manufacturing a custom fiberglass bumper or fender involves creating a mold of the desired shape using foam or other materials. Once molded, it is coated with a layer of fiberglass resin. After the fiberglass hardens, it is subsequently reinforced by adding additional layers of fiberglass or by structurally reinforcing it from the inside.
