THERMOPLASTIC REINFORCED COMPOSITE MATERIALS AND METHODS FOR PREPARING THE SAME Russian patent published in 2008 - IPC C08J5/04 B32B17/04 B32B27/02 B32B27/04 C08J5/24 

FIELD: composite materials.

SUBSTANCE: invention relates to preparation of thermoplastic reinforced polymeric composite materials and can be used in manufacture of structural-destination plastics suitable for use in different fields of mechanical engineering and shipbuilding, in aircraft and special industries as well as manufacturing profiled parts, e.g. thin- and thick-walled casings. Material according to invention contains alternating copolymer of carbon monoxide with olefins or dienes (polyketone), 0.4-7.0%, polymer film, 30-45%, and reinforcing fibrous filler, the rest, or composite material contains 0.4-40% polyketone and reinforcing fibrous filler. Preparation procedure: polyketone and film or polyketone only are applied on fibrous filler, after which coated filler is molded at 200-230°C and pressure 2-6 Mpa, and then cooled at a rate of 0.2-0.5°C/min. Invention enables obtaining nontoxic thermoplastic reinforced materials showing unlimited vitality and lack of corrosive effects on equipment during preparation of prepregs and composite material based thereon, which favors technological effectiveness of manufacture.

EFFECT: increased adhesion of polymeric binder if filler surface at minimum content thereof, which provides compatibility of material with all commercial thermoplastics.
