FRP pultruded profiles, there are many, fiberglass pipe, fiberglass pipe, rectangular pipe fiberglass, fiberglass rod, glass and steel I-beam. The basic components of the FRP profiles for a resin and glass fiber (including cloth, felt, etc.), which is based fibers (including glass fibers, carbon fibers, organic fibers and other metals, non-metallic fiber) as a reinforcing material, resin (mainly epoxy polyester resins, phenolic resins) as crosslinking agent and other auxiliary materials supplemented (the main materials: mold release agents, curing agents, catalysts, closed mold release agents, UV light stabilizers, mold clean water, plastic clothing, etc. ) composite made of. It has a high temperature, corrosion resistance, high strength, low specific gravity, low moisture absorption, good extension and a series of small and excellent insulation properties.

It has a high temperature, corrosion resistance, high strength, low specific gravity, low moisture absorption, good extension and a series of small and excellent insulation properties. After shrinkage has good dimensional stability in a thermosetting resin matrix forming a crosslinked network structure during processing integrated action of heat occurs, the article is dimensionally stable under normal good, that occur after the molding is small. Products under long term continuous loading minimal changes its shape and size, i.e., creep is small. Creep performance depends on the size of its load, the temperature level and duration of load factors of time. At a fixed load and temperature conditions, creep after prolonged loading thermosetting plastics smaller than thermoplastics. Superior heat temperature properties of thermosetting resin matrix composites can not be cured and then soften, heat resistance, and its products fairly stable, with a load of 1.86MPa, generally heat distortion temperature within 150 ~ 260 ℃, and fiber-reinforced thermosetting plastics belong to excellent insulating material, whose thermal conductivity is generally 0.35 ~ 0.47W / (mK), only the metal of 1/100 to 1/1000, it can be used as good heat insulation materials and the instant high temperature materials, heat distortion temperature of the material up to 350 ℃, can be used at room temperature and high temperature structural materials. Glass / phenolic rocket, missile engines excellent insulation. Excellent electrical properties of the composite material is excellent in electrically insulating material, mica is more excellent in terms of packing articles prepared for its electrical properties, can be used to manufacture the arc resistance, resistance, voltage, excellent specific inductive electrical components. Since the composite material has excellent electrical properties, and its products do not exist electrochemical corrosion and stray current corrosion, can be widely used in the manufacture instruments, motors and electrical insulating parts, in order to improve the reliability of electrical equipment and extend the life . In addition, the role of good products at high frequency and microwave dielectric properties of permeability has been used to produce a variety of high-frequency dielectric radome and other products. Excellent corrosion resistance resin-based composite materials and electrochemical corrosion mechanism different from ordinary steel, it is non-conductive, dielectric solution does not dissolve the ion, and thus the air, water and general concentration of acid, alkali, salt and other media has good chemical stability, especially in the non-oxidizing acid and fairly wide ph range of medium has good stability. Therefore, it is widely used in the manufacture of corrosion-resistant products, in order to deal with some of the media can not be used for stainless steel (such as hydrochloric acid, chlorine, carbon dioxide, sulfuric acid, sodium hypochlorite, and sulfur dioxide) corrosion, has played a good role. Glass steel garbage profiles good contact with the surface properties of the composite surface chemical media rarely produce corrosion generally rarely scaling, so commonly used manufacturing fluid conduit in its pipeline little resistance, low friction coefficient, saving a lot power. Because composites are generally not as easy as the metal to form metal ion contamination media, so this is also widely used in the food and pharmaceutical industries composite products reason. In addition, the composite material has a high friction (pv) limits under water lubrication conditions, the friction coefficient is very small, about 0.01 to 0.03, it is also the preferred material wearable products.
