SHORT FIBER FOR POLYAMIDE COMPOSITE AND POLYAMIDE COMPOSITE

摘要

PROBLEM TO BE SOLVED: To provide a short fiber for polyamide composite good in adhesiveness with a polyamide resin while maintaining high heat resistance and high Young modulus which a polyparaphenylene terephthalamide fiber originally has and capable of enhancing mechanical strength and abrasion resistance of a fiber reinforced polyamide resin (polyamide composite).SOLUTION: There are provided a short fiber for polyamide composite consisting of a polyparaphenylene terephthalamide short fiber by cutting a fiber composite obtained by penetrating a solution obtained by dissolving a resin having a functional group capable of reacting with an amide group into a hydrophilic solvent or a solution obtained by aqueous emulsifying it into a polyparaphenylene terephthalamide fiber skeleton having moisture amount adjusted to be 15 to 200 wt.% and heat treating it with a predetermined length and a polyamide composite by melting and mixing the same.SELECTED DRAWING: None
