Comprehensive Overview and Document Analysis of Basalt Fiber

Basalt fiber.docx

Basalt fiber is an inorganic fiber made from natural basalt through crushing, screening, shaping, and heat treatment. Its raw materials are widely distributed in the western plateau areas of China. Basalt fiber is an inorganic non-metallic material that has been widely used in composite materials and other composite materials due to its excellent physical and chemical properties. Basalt fiber is a porous silicate composed of carbon and oxygen elements, characterized by low density, high strength, and good corrosion resistance. Basalt fiber has become the preferred material for the application of carbon fiber in composite materials due to its unique properties. However, compared with carbon fiber, its price is higher, production technology is more difficult, and its high temperature resistance is insufficient. How to improve process technology, reduce production costs, and enhance the performance of basalt fiber in composite materials is currently the main problem facing us.

1 Product Introduction

Basalt fiberIt is an inorganic non-metallic material made from basalt mineral as raw material, which is crushed, washed, dried, ground, and then added to resin by impregnation or other methods, and melted at high temperature. It has a glassy structure.

Basalt fiber belongs to amorphous fibers and has the advantages of high strength and high modulus. As a new type of high-performance composite reinforcement material, it can improve the mechanical properties and thermal stability of composite materials. It has a wide range of applications, including lightweight structural components, high-strength composite structural components, and high-strength composite structural components for aircraft, automobiles, ships, and other transportation vehicles.

II Production process

The production process of basalt fiber can be divided into three types, namely the production process of native basalt fiber and the production process of modified basalt fiber. During the production of native basalt fibers, it is necessary to crush, screen, mix, and prepare the raw materials; The modified basalt fiber needs to undergo melt spinning treatment, and then the spinning solution is sprayed into the mixer for spinning.

III application area

Basalt fiber composite materials are mainly used for manufacturing industrial furnace linings, kiln linings, chimney linings, and can also be used for manufacturing ship, automobile, and building structural components. In addition, basalt fiber is also used as anti-corrosion lining, fireproof lining, etc., with a wide range of applications.

With the development of domestic aerospace industry, the demand for heat-resistant and high-temperature resistant materials for aircraft engines continues to grow. Basalt fiber has excellent properties such as high temperature resistance and corrosion resistance, and is widely used in the aerospace industry. At present, the main material used for aircraft engine blades in China is carbon fiber, while basalt fiber is still in the research and development stage, and industrial production has not yet been achieved domestically. With the development of China's aviation industry, the demand for basalt fiber will increase, so its future market prospects are very broad.

4 market prospect

Basalt fiber has a great advantage in price compared with carbon fiber. However, due to the complex production process and high production cost of basalt fiber, only a few enterprises can produce basalt fiber in China at present, and the output is also small. The output is mainly concentrated in Xizang Autonomous Region and Yunnan Province. With the development of technology and the continuous efforts of researchers, the production capacity of basalt fiber in China is expected to be improved in a few years.

5 Application Cases

At present, China has regarded basalt fiber as an important fiber-reinforced material and developed a series of high-performance composite materials and products, which are widely used in industries such as automobiles, aerospace, wind power generation, and sports goods. Among them, basalt fiber composite materials are particularly widely used in the field of wind power generation. In wind power generation, basalt fiber composite materials can not only enhance the blade structure and tensile strength, but also improve the fatigue performance and impact resistance of the blades. In addition, basalt fiber can also replace carbon fiber as a reinforcing material in composite materials, improving the mechanical properties of composite materials.
