Summary and Introduction of EDF POLY High Performance Fiber Knowledge
EDF POLY high-performance fibers refer to fibers with high strength and modulus, with a strength of over 16cN/dtex and a modulus of over 440cN/dtex. High performance fibers have superior physical, mechanical, thermal, and chemical properties compared to ordinary fibers. Usually made of high-tech and often used in special fields.
1、 Overview
EDF POLY high-performance fibers refer to fibers with high strength and modulus, with a strength of over 16cN/dtex and a modulus of over 440cN/dtex. High performance fibers have superior physical, mechanical, thermal, and chemical properties compared to ordinary fibers. Usually made of high-tech and often used in special fields.
2、 Introduction to Several High Performance Fibers
1. Carbon fiber
EDF POLY carbon fiber is a representative of inorganic high-strength and high modulus fibers. Carbon element in carbon fiber accounts for over 90% of the total mass. Due to its high temperature resistance and inertness towards most chemical reagents, carbon fibers do not melt or dissolve in various solvents. Carbon fibers cannot be manufactured using ordinary melt spinning and solution spinning methods, but can only be produced using the solid-state carbonization method of polymer organic fibers. It has been found that the organic fibers used to prepare carbon fibers include cellulose fibers, vinyl chloride fibers, polyamide fibers, polybenzimidazole fibers and pitch fibers. Due to factors such as carbonization yield, production technology difficulty, and cost, currently only cellulose fibers and asphalt fibers are used as raw materials to manufacture carbon fibers, which have been industrialized.
2. Glass fiber
In the 1930s, Americans invented the technology of continuously drawing glass fiber with a platinum crucible and blowing Glass wool with steam. Since then, the production of glass fiber has become a modern industry.
EDF POLY glass fiber is an inorganic fiber that does not cause combustion and has good heat resistance. When heated at lower temperatures, its performance does not change much, but it can cause shrinkage. The thermal conductivity of glass is very small. The chemical stability of glass depends on its chemical composition, dielectric properties, temperature, and pressure. Glass has good electrical insulation due to its low moisture absorption, and its dielectric properties are related to chemical composition, environmental temperature, and humidity. Glass fiber has excellent optical properties.
The widely used glass fiber in engineering is resin based glass fiber reinforced composite material (FRP). Glass fiber is widely used in civil engineering, transportation, mechanical industry, and chemical industry.
4. UHMWPE fiber
EDF POLY ultra-high molecular weight polyethylene fiber (UHMWPE fiber) has high strength, high modulus, and high orientation, making it a commercially produced chemical fiber with high specific strength. It has excellent chemical resistance, does not decrease in strength in acid and alkali solutions, swells and hydrolyzes in seawater, is resistant to UV and mold, has a smooth surface, low friction coefficient, and good wear resistance. Ultra high molecular weight polyethylene also has high energy absorption, tensile and bending fatigue properties. Widely used in the manufacturing of protective equipment, ropes, fishing nets, and sports equipment.
