Description

technical field [0001] The invention belongs to the scientific and technical field of polyetheretherketone composite materials, and in particular relates to a polyetheretherketone composite material and a preparation method thereof. Background technique [0002] Polyetheretherketone (PEEK) resin was first successfully developed and commercialized by the British ICI company in the early 1980s. After a period of development induction, it was exclusively operated by Victrex in 1993, and the output thereafter increased by 15% per year. . Polyether ether ketone is a kind of linear aromatic polymer compound. Its macromolecular main chain contains a large number of aromatic rings and polar ketone groups, which endow the polymer with heat resistance and mechanical strength; in addition, the macromolecule contains a large amount of ether Bonds, and endow the polymer with toughness, the more ether bonds, the better the toughness. Polyether ether ketone has the following characterist...
