Fiberglass Rods High tensile strength

Glass to some ideas for qualitative hard brittle object, is not suitable for as a structural material but as smoke into silk, is its strength increase greatly and has softness, so with resin fu and shape after finally can become the fine structure of the material. It can be seen that the strength of glass fiber decreases with its diameter. As the reinforcing material glass fiber has the following characteristics, these characteristics make the use of fiberglass far more widely than other kinds of fibers, and the development speed is far ahead of its characteristics:

(1) the tensile strength is high and the elongation is small (3%).

(2) high elastic coefficient and excellent rigidity.

(3) the elastic limit is large and the tensile strength is high, so the absorption shock energy is large.

(4) inorganic fiber, non-flammable, good chemical resistance.

(5) small absorption.

(6) stability and heat resistance.

(7) good processing ability, which can be used in various products such as stock, beam, felt and weaving.

(8) transparency can penetrate the light.

(9) development and completion of the surface treatment agent with good resin.

(10) the price is cheap. Glass fiber reinforced plastic (FRP) is a kind of compound plastic with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin as matrix materials. As a kind of composite material, FRP because of its unique performance advantages, in the aerospace, railway, building decoration, household furniture, building materials, sanitary ware and sanitation engineering has been widely used, and so on related industries.

According to the fiber used, glass fiber reinforced plastic is divided into glass fiber reinforced composite plastic (GFRP), carbon fiber, reinforced composite plastic (CFRP) and boron fiber reinforced composite plastic. It is made of glass fiber and its products (glass cloth, belt, felt, yarn, etc.) as the reinforcing material, and the synthetic resin as the matrix material. Fiber reinforced composites are made up of reinforced fibers and matrix. The diameter of the fibers (or whiskers) is small, usually less than 10 microns, which is brittle material, vulnerable, fractured and corroded. The matrix is elastic and elastoplastic, and is a ductile material. French saint-gobain group recently reported, 2006 global glass fiber production of about 3.2 million tons, of which reinforced thermosetting plastics with about 1.28 million tons, reinforced thermoplastics with 896000 tons, 514000 tons, textile wet mat with 510000 tons.

According to foreign reports, the annual growth rate of glass fiber in the world has remained at around 5% in recent years, of which the United States was 2.5% in 2002-2007, 4% in Europe, 7% in Asia and 10% in China.

If the annual growth rate is increased, the global total output of glass fiber will be about 3.9 million tons in 2010.

The world of glass fiber abroad is wonderful, the products are changing rapidly and dazzling. Now has more than 5000 varieties, more than 60000 specifications, use in electronics, communications, construction, chemical, metallurgy, nuclear energy, aviation, aerospace, weapons, ships, transport and Marine development, new and high technology fields such as genetic engineering, it is no exaggeration to say, it's "footprint" is up to nine days "" reach", down to the penta-ocean "catch turtle", has become indispensable to the 21st century global sustainable development of high and new functional materials and structural materials.

It is reported that the global total output of glass fiber is growing by an average of 160-200,000 tons per year, and the varieties and specifications are developing at an average annual growth of 1000-1500.

Glass fiber products abroad, divided according to the use basically can be divided into four categories: with glass fiber reinforced thermosetting plastics products, with glass fiber reinforced thermoplastics products, enhance the asphalt by using glass fiber products and glass fiber textile products.
