FIELD: chemistry.
SUBSTANCE: described is method for obtaining carbon fibre-reinforced polymer based on heat-resistant binding agent, in which phthalonitrile binding agent in form of powder is placed on the surface of fibrous carbon filler, selected from carbon full-strength or monodirectional tissue, filler is soaked with thereof, and mould carbon fibre-reinforced polymer is moulded in mould from binder-soaked filler. Preform is moulded by application of filler layers one on another with their mutual fixation by solution of cyanic ether in acetone in quantity 3-10 wt % of cyanic ether to filler weight, preform is placed in mould, binding agent is placed in form of powder on the surface of preform or between layers of filler vacuum soaking of preform with molten binding agent, after that, carbon fibre-reinforced polymer is formed from preform in mould in mode of stepped heating with the following thermal processing of carbon fibre-reinforced polymer in inert atmosphere.
EFFECT: provision of possibility for production of complicated-profile products based on carbon fibre-reinforced polymer with exploitation temperature to 400 degrees, reduction of loss of binding agent in the process of obtaining carbon fibre-reinforced polymer, provision of possibility of acute setting of component ratio in obtained carbon fibre-reinforced polymer with preservation of physical-mechanical characteristics at high level.
