Glass fiber noun analysis

Glass fiber is an essential material for the composition of glass fiber tubes. This section introduces the related terms of glass fiber.

【Artificial Glass Fiber】

It refers to artificially melting the melt by external force, stretching and cooling, and hardening into a fibrous unit of amorphous structure. It is usually a general term for fiberglass and mineral wool. Also included in the broadest sense are man-made elemental glass fibers, plexiglass fibers, and other inorganic glass fibers.

【glass fiber】

An artificial inorganic fiber. Use natural ore such as quartz sand, limestone, self-cloud stone, kaolin, pyrophyllite, etc., together with other chemical raw materials such as soda ash, acidity (also can be replaced by alkali, containing natural ore), etc., into glass, In the molten state, it is drawn, blown or twisted into a very fine fibrous material by external force. According to its composition and properties, it can be divided into non-alkali glass fiber (including non-stretched raw glass fiber), medium alkali glass fiber, high alkali glass fiber and special glass fiber; according to its form, it can be divided into continuous glass fiber and fixed length fiberglass. And glass wool; according to the production method, there are basically two types: one is to make the molten glass directly into the fiber, and the other is to make the molten glass into a ball, a rod or a block, and then use it as a raw material, and use various heating methods. After remelting, it is made into fibers. The basic properties of glass fiber are: non-combustible, corrosion-resistant, high-temperature resistant, low hygroscopicity, small elongation, high tensile strength, good chemical stability, good electrical insulation and thermal insulation properties, and poor flexibility and folding resistance. Due to the different glass composition, the performance of one aspect can be more prominent. It can be made into various forms of products, such as yarn, wool yarn, cloth, tape, circular cloth, mat, felt, board, shell and so on. It can be used as electrical insulation materials, filter materials, heat insulation, sound absorption, shock absorption materials, anti-corrosion materials, moisture-proof materials, etc.; and it can be used as a reinforcing material to make composite materials with various organic or inorganic materials, such as glass fiber reinforced thermosetting plastics. (Glass steel), glass fiber reinforced thermoplastics and reinforced rubber products, glass fiber reinforced inorganic cementitious materials such as reinforced plaster and cement; organic coating treatment can also be used to improve its flexibility, making various soft products such as packaging cloth, Screens, curtains, wall coverings, tarpaulins, architectural membranes and special protective equipment. These products are widely used in industrial, agricultural, construction and civil applications. And because it has some excellent properties that other materials do not have, it has become an indispensable material in the military industry.

[Continuous glass fiber]

A large category classified by fiberglass morphology. When the molten high-temperature viscous glass liquid flows out of the pupil, it is drawn into an infinitely long glass fiber by an external force. Continuous glass fibers have different thicknesses and their uses are different. Generally, fibers of 3 -9 μm in diameter are woven into various textile products, such as cloth, belts, sleeves, etc., which are often referred to as textile-type glass fibers because they are often subjected to textile processing; they are made of fibers having a diameter of 10 -24 μm. It is a reinforcing material such as roving, roving, chopped strand, chopped strand mat. Therefore, it is also called enhanced glass fiber.

[fixed length fiberglass]

Automotive carbon fiber composite materials will surpass metal materials

Japan and the United States dominate most of the world’s carbon fiber production capacity and control the production of high-end carbon fiber. Toray started in the development and production of PAN-based carbon fiber and is the representative of Japanese carbon fiber production enterprises. At present, the world’s major producers of small tow carbon fiber include Japan Toray, Japan Toho Rayon, and Japan’s Mitsubishi Rayon. Although the US company has less output, it is still technically comparable to the three huge Japanese companies.

Automotive carbon fiber composite materials will surpass metal materials

Before and after the development of carbon fiber by Toray, China began to independently develop carbon fiber. Although China has become the world’s largest producer of fiberglass, unfortunately, after nearly 40 years of development from mid-1970s, China’s carbon fiber industry’s development and production level lags behind, which is unable to compete with the US and Japan companies.

According to estimates, under the same cruising range, the weight of electric vehicles is more than 200~300kg or more than traditional vehicles. Therefore, in order to ensure that the electric vehicle has a good cruising range and affordable cost, the weight of the electric vehicle must be reduced by more than 50%. Among all lightweight materials, carbon fiber is the only advanced material that can reduce the weight of steel parts by 50-60% while providing the same strength.

Automotive carbon fiber composite materials will surpass metal materials

Carbon fiber reinforced composites have excellent physical properties: 30% lighter than aluminum, 50% lighter than steel, and 7 to 9 times stronger than steel. They were first used in high-tech fields such as aerospace, and military. It is recognized that CFRP (carbon fiber reinforced composite material) is the best material to solve the weight loss of new energy vehicles. The use of carbon fiber can make vehicles lose weight by 30% to 60%, It is a new energy source, and the leader of the vehicles’ “slimming revolution”, which plays a key role in vehicles lightweighting.

Throughout the current development of the new energy vehicles industry, it can be found that the wide application of carbon fiber composite materials in new energy vehicles is an inevitable result. it is also an inevitable choice for new energy vehicles companies to carry out automobile production and manufacturing.

Automotive carbon fiber composite materials will surpass metal materials

“Materials can change our lives.” As the slogan of Toray, carbon fiber and carbon fiber reinforced composites that contribute to energy conservation and greenhouse gas reduction. Toray holds about half of the world’s share of polyacrylonitrile-based carbon fiber. The technicians engaged in the development of Toray have long established carbon fiber-made vehicles and airplanes with the market targets of vehicles, airplanes, and atomic power generation. Toray started with sports and leisure products, and changed the use of carbon fiber for vehicles, airplanes and wind turbines at the same time.

Toray shows: There are two things that can surpass the automotive industry or bring the automotive industry to a higher level in the future: one is artificial intelligence, and the second is carbon fiber lightweight, which uses carbon fiber composites to surpass metal materials.
