    The three advantages of FRP products

    Issue Time:2011-11-17

      FRP products is a new composite material. It is unique in the materials science community. In fact, neither glass FRP, not steel, it is a polymer matrix organic resin, glass fiber or other fabric reinforced. Because it has a glass-like transparency or translucency, with high-strength iron is named. Its scientific name is glass fiber reinforced plastic.
      FRP has three advantages:
      First, FRP density, strength, strong than steel, lighter than aluminum, weight is only 1/4-1/16 of ordinary steel, and mechanical strength is 3-4 times that of steel;
      The second is a moment of high temperature properties of FRP;
      Third, with good acid and alkali resistance properties and not magnetic.
      Because
    FRP products with the many excellent features, so it was born half a century, ever-changing variety of new products, applications in various fields growing.
      Because of its small proportion of high strength, naturally favored in the aviation industry. Since 1944, the first steel frame with glass as the main structural material of the aircraft subjected to a rigorous flight test, the glass fiber reinforced plastic in the aviation industry consolidated our position. From the fuselage, wings to the tail, doors, windows, etc. more and more metal aircraft parts were replaced by fiberglass material. At present, many light aircraft replaced the main components of glass reinforced plastic products, even on a Boeing 747 jet, there are ten thousand glass parts made of steel too!
      The first manned in 1947 fiberglass boat into the water. It was only 8.5 meters long. Now a growing number of world sailing, yacht, boat transportation, boat, fishing vessel and minesweeper so use glass steel. Even in the aircraft carriers, cruisers, tons wheel and other large ships, and fiberglass parts are everywhere.
      FRP in the ocean, into the sky, but also launched a challenge to land transportation, all kinds of glass fiber reinforced plastic automotive parts came into being. Italy, France and many other well-known car companies manufacturing auto fiberglass shell has reached hundreds of million.
      Because of its excellent corrosion resistance, in the chemical industry, glass, steel reaction tank, tanks, mixers, pipes, etc. displayed their prowess, saving a lot of metal.
      FRP growing role in the construction industry. Many of the new stadium, exhibition hall, a huge commercial roofs are made of steel by the glass. It is not only lightweight, high strength, but also through the sun too! 1980s, suburban Miyun County in Beijing, China built a FRP highway bridge. The bridge span 20.24 m net, full width 9.6 m, two lines of 20 tons can pass or a 80 t truck fleet heavy flatbed trailer. The bridge's superstructure with a total glass cloth, resin, glass, steel and other materials about 22 tons, with auxiliary materials, only 30 tons, described as the world's lightest bridge it!
      
    FRP products in many areas have shown its strong vitality.
