Advantages and disadvantages of FRP materials

one. Advantages of the FRP material
1. Bright, high wear resistance, only 1.52. Only 1 / 41 / 5 of carbon steel, but the tensile strength is close to, even more than carbon steel, can be compared with excellent carbon steel.
2. Good corrosion resistance, good corrosion resistance, gas, water, acid, alkali, salt, as well as a variety of oil and organic solutions have a strong immunity.
3. Excellent production process can be applied according to the product appearance, standard and the quantity of soft molding process; the production process is simple, can be plastic products, outstanding economic benefits, especially complex appearance, not easy to cause a small number of products, technology and sense of honor is more prominent.
4. Appearance design patent scheme design of high quality, rich material selection, to achieve product performance, flexible scheme design, various structures of products and product requirements, so that the product is intact.
two. Disadvantages of the FRP material
1. Aging phenomenon is a common disadvantage of plastic, except glass fiber reinforced plastic, in ultraviolet light, sand wind, rain and snow, chemical substance analysis, mechanical stress, and other aspects, it is easy to cause performance melting.
2. The long-term temperature difference of general FRP can be used for a long time at high temperature, the tensile strength of 50℃ is significantly reduced, generally only used for 100℃; general epoxy resin rubber FRP over 60℃, the tensile strength is significantly reduced. However, continuous high temperature epoxy resin adhesive can be selected to make the long-term working temperature 200300℃.
3. The ductile grinder is low. The ductile grinder of glass fiber reinforced plastic is twice that of logs, but 10 times that of steel (E=2.1 * 106), so it is generally difficult to deform in the product structure. It can also be made of bionic buildings and decorative partition structures, or can be composed of high modulus chemical fiber or lifting ribs.
