FRP is a kind of composite material developed rapidly in the past more than 50 years. 70% of the output of fiberglass is used to make fiberglass. FRP has a high hardness, much lighter than steel. It can be used as a fuel tank and pipeline to reduce the weight of the aircraft. The astronauts aboard the moon, the miniature oxygen cylinders they carry on their backs, are also made of glass steel. FRP processing is easy, not rust not rotten, do not need paint. China has widely used FRP manufacturing all kinds of small boats, lifeboats, yachts, as well as automotive manufacturing, saving a lot of steel.
