Title:
CARBON-FIBER-REINFORCED COMPOSITE MATERIAL FOR MAKING MUSICAL INSTRUMENT, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/114484
Kind Code:
A1
Abstract:
Disclosed are a carbon-fiber-reinforced composite material for making a musical instrument, and a preparation method therefor, which relate to the field of materials. The carbon-fiber-reinforced composite material comprises, in parts by weight: 20-80 parts of an acrylonitrile-butadiene-styrene copolymer, 15-35 parts of carbon fibers, and 5-30 parts of an acrylonitrile-styrene copolymer. The preparation method comprises: mixing, in parts by weight, the acrylonitrile-butadiene-styrene copolymer and the acrylonitrile-styrene copolymer with an auxiliary agent to obtain a mixed material; and mixing the mixed material with the carbon fibers, and then extruding and pelletizing same. The carbon-fiber-reinforced composite material prepared by the method has higher specific strength, flexural modulus, and impact strength, enabling the musical instrument made therefrom to have good tone quality and quality, and also improving the production efficiency of the musical instrument.
