Abstract

The invention discloses a carbon fiber reinforced polyamide composite material comprising the following components in parts by weight: 100 parts of polyamide resin, 100 to 250 parts of carbon fibers,2-18 parts of an ethylene-methacrylic acid copolymer derivative, and 0.1-10 parts of calcium chloride and / or lithium chloride. A specific ethylene-methacrylic acid copolymer derivative is selected, and the crystallinity after impregnation is adjusted through calcium chloride and / or lithium chloride, so that the carbon fiber reinforced polyamide composite material has low porosity in the preparation process, and the mechanical property of the material is improved.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a carbon fiber reinforced polyamide composite material and a preparation method thereof. Background technique

[0002] Due to the characteristics of high strength, high modulus, high impact resistance, and 100% recyclability, continuous fiber-reinforced thermoplastic composites have gradually replaced metal or thermosetting composites in various industries, such as carbon fiber-reinforced special engineering plastics, such as PPS , PEEK, PEI, etc., have been widely used in civil airliners. Continuous glass fiber reinforced polypropylene, polyethylene, polyamide and other composite materials are also maturely used in refrigerated container lining boards, auto parts, RTP pipes and other fields. Continuous carbon fiber polyamide composites have excellent mechanical properties and temperature resistance, so they have great development potential in the lightweight of automo...
