NOVELTY - Multifunctional composite fiber material comprises 10-20 pts. wt. ceramic powder, 30-50 pts. wt. polycaprolactone fiber, 7-12 pts. wt. hydrated magnesium silicate, 6-15 pts. wt. polypropylene fiber, 4-8 pts. wt. polyamide fiber, 2-5 pts. wt. graphene nano powder, 4-7 pts. wt. snowdrop peel powder, 3-7 pts. wt. mica powder, 2-6 pts. wt. egg yolk powder, and 50-80 pts. wt. solvent. The multifunctional composite fiber material is prepared by pulverizing ceramic powder, hydrated magnesium silicate, polypropylene fiber, and polyamide fiber to obtain nanofibers. The nanofibers are placed into autoclave. The solvent is added and mixed well. The polycaprolactone fiber, graphene nano powder, snowdrop peel powder and mica powder are added into the high-pressure reaction kettle, sealed and stirred reaction under pressure. USE - Multifunctional composite fiber material is used in machinery, metallurgy, chemical industry, petroleum, ceramics, glass, electronics and other industries. ADVANTAGE - The multifunctional composite fiber material has high strength, strong corrosion resistance and flexibility, and good characteristics. DETAILED DESCRIPTION - Multifunctional composite fiber material comprises 10-20 pts. wt. ceramic powder, 30-50 pts. wt. polycaprolactone fiber, 7-12 pts. wt. hydrated magnesium silicate, 6-15 pts. wt. polypropylene fiber, 4-8 pts. wt. polyamide fiber, 2-5 pts. wt. graphene nano powder, 4-7 pts. wt. snowdrop peel powder, 3-7 pts. wt. mica powder, 2-6 pts. wt. egg yolk powder, and 50-80 pts. wt. solvent. The multifunctional composite fiber material is prepared by pulverizing ceramic powder, hydrated magnesium silicate, polypropylene fiber, and polyamide fiber to obtain nanofibers. The nanofibers are placed into autoclave. The solvent is added and mixed well. The polycaprolactone fiber, graphene nano powder, snowdrop peel powder and mica powder are added into the high-pressure reaction kettle, sealed and stirred reaction under pressure. The egg yolk powder is added in the reaction kettle, then air-tightly seal reaction and dried to obtain high-strength precursor fibers. The high-strength precursor fibers is added in autoclave under critical conditions, and reaction is heated to obtain high-strength composite fibers.
