Abstract In this paper, the problem of increasing the strength and elastic modulus of unidirectional structural glass-fiberreinforced plastic (GFRP) is considered and the possibilities of using hybrid reinforcement based on GFRP and high-strength steel cord wire are discussed. Static tensile testing of laboratory samples of metal-glass-reinforced plastics was performed, the results of which show the significant dependence of the mechanical characteristics on the adhesion of both filler components to the binder. To realize high mechanical characteristics of the metal-glasspolymer composites under consideration, it is necessary, besides ensuring strong adhesion of filler to binder, to create a certain gradient of the elastic modulus of the intermediate layer near the surfaces of the components using bionic principles for constructing high-strength natural joints.
