Abstract

The invention discloses a carbon fiber reinforced polyetherimide (PEI) / polyphenylene sulfide (PPS) composite material. The carbon fiber reinforced polyetherimide / polyphenylene sulfide composite material comprises polyetherimide, polyphenylene sulfide, carbon fibers and lubricant. The invention also discloses a preparation method of the carbon fiber reinforced polyetherimide / polyphenylene sulfide composite material. According to the preparation method, the PPS and the PEI are adopted and prepared into the PEI / PPS alloy material, thereby the solvent resistance, the heat resistance and the processing fluidity of the PEI can be obviously improved, and the material cost of the PEI can also be reduced.

Description

technical field [0001] The invention relates to the preparation technology of polymer composite materials, in particular to a carbon fiber-reinforced polyetherimide / polyphenylene sulfide composite material with high temperature resistance, high strength, high modulus, chemical solvent resistance and impact resistance and its Preparation. Background technique [0002] Polyetherimide (referred to as PEI) is a kind of thermoplastic special engineering plastics. It was researched and developed by General Corporation of the United States in 1972. After 10 years of trial production, it was introduced to the world market under the trade name Ultem in 1982. The molecular structure of PEI contains both aromatic amine functional groups and ether structures. Compared with other aromatic PIs, it is a thermoplastic PI with low cost and high output. PEI has excellent flame retardancy (oxygen index greater than 47, low smoke emission), toughness, radiation resistance, long-term heat resis...
