High performance fibers can be divided into corrosion-resistant fibers, high-temperature resistant fibers, flame resistant fibers, high-strength and high modulus fibers, functional fibers, and elastic fibers according to their properties.
Definition: Glass fiber seam woven felt, hereinafter referred to as seam woven felt, is composed of untwisted roving or checkered cloth arranged in a certain direction as the base material, which is cut into a certain length, evenly laid without direction, and sewn with organic fibers.
High performance fiber refers to the chemical fiber with special physical and chemical structure, performance and use, or with special functions. It generally has extremely high tensile strength, Young's modulus, and also has other characteristics such as high temperature resistance, radiation resistance, flame resistance, high pressure resistance, acid resistance, alkali resistance, oxidant corrosion resistance, etc. It is widely used in aerospace, national defense and military industry, transportation, industrial engineering, geotechnical engineering Even in fields such as biomedicine and electronics.
The clutch is located in the flywheel housing between the engine and gearbox, and the clutch assembly is fixed on the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. During the driving process of the car, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine and gearbox, in order to cut off or transmit the power input from the engine to the gearbox, The clutch is a commonly used component in mechanical transmission, which can separate or engage the transmission system at any time.
Core spun yarn, also known as composite yarn or wrapped yarn, is a new type of yarn composed of two or more fibers. Generally, a yarn is spun with synthetic fiber filaments with good strength and elasticity as the core, wrapped with short fibers such as cotton, wool, and viscose fibers, and twisted together. Core spun yarn has the excellent function of both filament core spun yarn and short fiber wrapping.
Core spun yarn is generally made by twisting synthetic fiber filaments with good strength and elasticity as the core, and wrapping them with short fibers such as cotton, wool, and viscose fibers. The core-spun yarn has the excellent performance of both filament core-spun yarn and wrapped short fibers. A common core spun yarn is polyester cotton core spun yarn, which uses polyester filament as the core yarn and is wrapped with cotton fibers. There is also spandex core-spun yarn, which is made of spandex filament as the core yarn and wrapped with other fibers. Knitted fabrics or jeans made of this core-spun yarn can stretch and fit comfortably when worn.
Glass fiber powder is mainly used to enhance thermoplastic materials. Due to its good cost-effectiveness, it is particularly suitable for composite with resin as a reinforcing material for the shells of automobiles, trains, and ships. So where else can it be used. Glass fiber powder is used for high-temperature needle punched felt, automotive sound-absorbing film, hot-rolled steel, etc. Its products are widely used in fields such as automobiles, construction, aviation daily necessities, and typical products include automotive parts, electronic and electrical products, mechanical products, etc.
High performance fibers are ideal reinforcements for advanced composite materials. Their development and application have played a significant role in promoting the development of the field of materials science and have been favored by people. Their application scope is also constantly expanding, reflecting a country's technological level and comprehensive strength. However, the development of high-performance fibers in China started relatively late and currently mainly relies on imports. Therefore, it is necessary to increase research and development efforts on high-performance fibers to improve China's technological level. The key goals for the future development of high-performance fiber industry are mainly reflected in the following aspects:
