Abstract: Carbon fiber reinforced plastics based on thermoplastic partially crystalline fusible polyimide R-BAPB and oligoimide IDA (diacetyl imide) have been obtained. The thermal, thermomechanical and mechanical properties of carbon plastics based on polyimides have been studied. It has been shown that carbon plastics based on the used polyimide binders have increased crack resistance, which makes it possible to operate them at temperatures up to $\sim$400$^\circ$C.

Keywords: carbon fiber reinforced plastic, polyimide binder, electrostatic spraying, interlaminar fracture toughness.
