Fiberglass reinforced plastic (FRP), also known as GFRP, is fiber reinforced plastic, which generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics reinforced with glass fiber or its products are called glass fiber reinforced plastics or FRP, which are different from tempered glass

FRP is a composite material that has developed rapidly in recent decades. 70% of fiberglass production is used to make fiberglass. FRP has high hardness and is much lighter than steel. Jets are used as fuel tanks and pipes, which can reduce the weight of the aircraft.

FRP is easy to process, not rusted and not rotten, and does not require paint. FRP is widely used in my country to manufacture various small motor boats, lifeboats, yachts and automobile manufacturing, saving a lot of steel. As FRP is a composite material, its performance adapts to a wide range, and the market development prospect is broad.

After more than 40 years of development, In China FRP industry has been successfully applied to various fields of the national economy and played an important role in economic construction.

FRP bolts are mainly made of glass fiber yarn, resin, curing agent and other materials. In the process of finishing the machining, many different processes are also used, such as extrusion, drawing and high temperature curing, and the machined shape is full thread.
