Enhancing material performance: When compounded with resin to form fiberglass reinforced plastic (FRP), it can greatly improve the impact resistance of the material and highlight the advantage of lightweight; when compounded with cement to make glass fiber reinforced concrete (GRC), it can effectively improve the crack resistance of the material.

Functional applications: It can be used to make circuit board substrates and wire sleeves by virtue of its insulation; it can be used to produce fireproof cloth and thermal insulation cotton relying on its high temperature resistance and non-combustibility; and it can be made into environmental protection filter materials with its corrosion resistance.

FRP (a composite of glass fiber and resin) is composed of organic resin and inorganic fibers, with complex components, making recycling difficult. The current mainstream recycling applications are as follows:  Waste Pretreatment
1.Dual-shaft shredder: The collected FRP products are transported to a dual-shaft shear crusher through a feeding belt or a metal chain plate machine and shredded into small pieces.	2.Hammer mill: The shredded pieces are sent to a single-shaft fine crusher through a belt conveyor and further crushed into strips.	3.Impurity removal: Magnetic separation equipment is used to remove metal impurities.

Resin in FRP may release trace harmful gases during crushing, so operations should be carried out in a well-ventilated environment, and dust removal equipment should be installed if necessary. The impurity content (such as metal and oil stains) of recycled strips or powders must be strictly controlled to avoid affecting the performance of secondary products. At present, physical recycling is mainly applicable to low-value-added scenarios. In the future, it is necessary to combine chemical recycling (decomposing resin and separating glass fiber) technology to improve the reuse value of fibers, such as reusing them in composite material production.
