The application prospects of carbon fiber composites in the automotive field are optimistic 2021-07-09
According to relevant information, BMW will use CFRP (Carbon Fiber Reinforced Plastic) carbon fiber composite materials in its i3 production car in 2013, and its choice is a slightly lower grade industrial-grade CFRP material, and the cost can be controlled by traditional carbon fiber materials. About half of it.
Rapid growth in demand, the era of carbon fiber is coming 2021-07-09
As a fibrous carbon material, carbon fiber has a carbon content of more than 90%. The material is black, hard, and has the characteristics of high strength and light weight. The specific gravity of carbon fiber is less than 1/4 of that of steel. The tensile strength of carbon fiber resin composites is generally above 35,000 MPa (MPa), which is 7.9 times that of steel. The tensile modulus of elasticity is 230,000-430,000 MPa, which is higher than that of steel.
Material introduction of tantalum carbide 2021-07-09
Metal matrix composites have received extensive attention from scientists in the field of materials of various countries due to their unique advantages of high specific strength, high specific modulus, wear resistance and high temperature resistance. At present, the research on metal matrix composite materials is mainly focused on the overall uniform composite, but because the wear only occurs on the surface of the part, the overall composite is not conducive to the recovery and reuse of the material and causes pollution to the environment. On the other hand, many studies have shown that wear-resistant materials need to have both high hardness and high toughness, while the overall composite only improves the hardness, but cannot improve the toughness, while the metal-ceramic composite material maintains the high hardness and high toughness of ceramics. Excellent performance such as wear resistance, and high toughness and high ductility of the metal matrix.
Application areas of tungsten carbide 2021-07-09
It is widely used as high-speed cutting tools, kiln structure materials, jet engine parts, cermet materials, resistance heating elements, etc.

The chemical properties of zirconium carbide 2021-07-09
Dark gray cubic crystals with metallic luster. Brittle. The melting point is 3540°C. The boiling point is 5100°C. The apparent density is 6.70 g/cm3. Mohs hardness 8-9. Insoluble in cold water and hydrochloric acid. It is soluble in hydrofluoric acid and hot concentrated sulfuric acid containing nitric acid or hydrogen peroxide. It reacts with chlorine at high temperature to produce zirconium tetrachloride. At 700°C, it burns in the air to produce zirconia. Does not react with water.
Uses of titanium carbide 2021-07-09
1. Used as additives for cutting tool materials and metal bismuth, zinc, and cadmium melting crucibles to prepare semiconductor wear-resistant films, HDD large-capacity memory devices.
Physical and chemical properties of niobium carbide 2021-07-09
Is insoluble in hot and cold hydrochloric acid, sulfuric acid, nitric acid, but soluble in a mixed solution of hot hydrofluoric acid and nitric acid. It is stable at 1000~1100℃, and rapidly oxidized to niobium pentoxide above 1100℃. Niobium carbide is easy to melt in titanium carbide, zirconium carbide, tungsten carbide and other compounds, and together form isomorphous solid solution mixtures. Melting point: 3500℃, density: 7.6g/cm³(25℃)
Application fields of molybdenum carbide 2021-07-09
From the perspective of the global consumption structure, molybdenum is indeed an ally of iron. 80% of the demand for molybdenum in western developed countries comes from steel, stainless steel absorbs 30% of molybdenum, low-alloy steel absorbs 30%, drill bits and cutting tools account for 10%, and cast steel accounts for 10%. Another 20% of molybdenum consumption is in molybdenum chemicals, molybdenum-based lubricants and petroleum refining. Quite typically, the proportion of molybdenum consumption in steel production in the United States in 1998 was 75%.
Uses of chromium carbide 2021-07-09
1. It is a kind of high melting point material with good wear resistance, corrosion resistance and oxidation resistance in high temperature environment. It is made of nickel-chromium alloy with cemented carbide particles. Plasma spraying method can be used as high temperature resistance and resistance. Abrasion, oxidation and acid resistant coatings are widely used in aircraft engines and petrochemical machinery components, which can greatly increase the life of the machinery. It is also often used as a grain refiner for cemented carbide and other wear-resistant and corrosion-resistant components. Cermets based on Cr3C2 have excellent oxidation resistance at high temperatures.
