Abstract

Modification of epoxy binders with butadiene-styrene thermoplastic elastomers was used to obtain functional-gradient carbon plastics with increased impact resistance. Samples were made and comparative tests of carbon fiber-reinforced plastics for resistance to impact loads and compression after impact were carried out. It is shown that smooth change of modifier concentration at transition from the external surface of the part to the internal one allows to increase effectively the impact strength of carbon fiber-reinforced plastic while maintaining the rigidity of the composite material.
