Glass fiber is mainly made from waste glass or quartz sand. Production of glass fiber must go through several processes. The raw materials are heated at high temperature from 1100 - 1300 degrees C until they turn into molten liquid. Through ultra-fine pores, the molten liquid forms very thin glass fiber which is measured in micrometers.

Glass fiber has the same raw material as the glass cups and glass windows have. Glass is not easy to decompose in nature, and so is glass fiber. There are several ways to decompose substances, such as weathering, erosion, bacterial and microbial decomposition. Since glass fiber is an inorganic material, it is not attacked by bacteria, microorganism and corrosion. Nothing in nature can break it down.

Fiberglass reinforced plastic (FRP) is a kind of plastic. FRP is made from glass fiber materials (fiberglass woven roving and fiberglass mat) and chemical resins. FRP is a very strong material that can compare with metals. Metals are strong materials, but they are easy to rust and corrode under wet conditions. However fiberglass is a non-metallic fiber material. It has very good chemical stability and can not react with many chemical substances. It is a corrosion resistance material and will not rust and corrode.

Most fiberglass reinforced plastic products are designed to be used for a long time. During the processes, resins and additives are used. These materials make FRP products very strong and durable and more difficulty to decompose. Glass fiber is a material that is indeed not easily degraded naturally, but this does not mean that FRP products can be used forever without damage. If it is used improperly, it will shorten its service time. For example, if it is exposed under the sun and very wet environment for a very long time, it may occur aging, deformation or cause other damage. In addition, if the glass fiber is subjected to strong force impact or friction, there may also be damaged and destroyed. So, when we use fiberglass products, we must protect them from strong force impact and we need to regularly maintain them and extend their service life as long as possible.
