Do you have any understanding of EDF POLY high-performance fibers?

EDF POLY high-performance fibers generally refer to fibers with strength greater than 17.6cN/dtex and elastic modulus greater than 440cN/dtex. High performance fiber is a new generation of high strength, high modulus, high temperature resistant Synthetic fiber developed from fiber science and engineering. High performance fibers have special properties that ordinary fibers do not possess, and are mainly used in various fields of military and high-tech industries.

EDF POLY high-performance fiber is a special type of fiber with excellent mechanical properties, with a strength of 18cN/dtex (20g/D) and an initial modulus of 441cN/dtex (500g/D). The main varieties include organic fiber para aramid, fully aromatic polyester, ultra-high molecular weight high-strength polyethylene fiber, and new type of polybenzimidazole. Inorganic fibers are mainly carbon fibers.

The production process of EDF POLY high-performance fiber is different from that of conventional Synthetic fiber, such as liquid crystal dry wet spinning of para aramid fiber, gel spinning of high-strength polyethylene fiber, combustion carbonization of carbon fiber, etc. All these bring Synthetic fiber technology into the high-tech category. In addition, composite materials made of thermoplastic resin, thermosetting resin, and various woven fabrics reinforced with high-performance fibers have gradually expanded their applications in fields such as aviation, aerospace, transportation, industrial production, agriculture, forestry, marine and aquatic products, energy, environmental protection, communication, medical and health, and sports equipment. Provide material conditions for the new era of humanity and enrich human life. Advanced composite materials composed of high-performance fibers as reinforcing materials have been widely used, promoting technological and economic development.

EDF POLY high-performance fibers have special properties that ordinary fibers do not possess and are a good engineering material. Its characteristics are as follows:

(1) High mechanical performance. High strength and high elastic modulus. The advancement of fiber materials has made it possible to manufacture advanced composite materials. Elastic modulus is an important indicator for measuring materials. For example, the commonly used steel fiber in engineering is 200GPa, the titanium alloy used in aircraft manufacturing is 106GPa, the aluminum alloy is 71GPa, the modulus of PPTA fiber is 132GPa, and the PBO fiber is as high as 280GPa. (2) High performance fibers have special applications in heat resistant protective materials due to their high temperature resistance, stable size at high temperatures, and low thermal shrinkage.

(3) Another advantage of high-performance fibers is their low density, which is beneficial for lightweight products.

(4) Organic high-performance fibers are easy to process and shape.

(5) Corrosion resistance of organic and inorganic high-performance fibers.

Most EDF POLY high-performance specialty fibers are made through wet spinning. Some fiber preparation processes are more difficult, such as using traditional spinning techniques to spin linear or low molecular weight fibers, followed by cyclization, cross-linking, metal chelation, high-temperature heat treatment, surface physicochemical treatment, or plasma treatment. To obtain finished fibers. Others need to adopt new spinning technologies, such as lotion spinning, reactive spinning, liquid crystal spinning, dry jet wet spinning, phase
