The idea itself wasn’t new. Chemist Leo Baekeland, who invented the first synthetic plastic Bakelite in 1907, used asbestos fibers to reinforce the product. During WWII, glass fibers were embedded in various resins to create the first examples of FRP using fiberglass. The early examples were used exclusively in military applications

· The Glass fibers used in concrete (see picture below) are made from alkali-resistant glass. This stems from the composition of glass, primarily silica. In an alkaline environment like concrete, which typically boasts a pH ranging between 12 and 13, regular glass could quickly deteriorate due to the alkali-silica reaction (ASR).

Fiberglass is made by adding resin to the glass fibers. Different resins can then be added to make the product stronger, tougher, and less brittle. Fiberglass can easily be molded into a variety of shapes and is incorporated into many industrial products due to its malleability and durability, including everything from equipment shelters to ducts to airplanes.

To create glass fibers, different minerals (silica sand, limestone, kaolin clay, dolomite, etc.) are melted in a furnace until they reach the melting point. Then, the melted glass is extruded through tiny brushings. These take the form of very small orifices – typically no more than 25 micrometers in diameter.
