HYBRID COMPOSITE REINFORCEMENT Russian patent published in 2017 - IPC E04C5/07 

FIELD: measuring equipment.

SUBSTANCE: hybrid composite reinforcement consists of continuous glass or carbon fibers assembled in a single rod by means of a multicomponent epoxy binder. The multicomponent binder content comprises 13-17%, and the volume content of carbon fibers - 3-15% by volume of the composite rod, carbon fibers being uniformly arranged along the reinforcement section contour at the distance from the reinforcement section edge equal to 2-3 mm; the rest of the composite reinforcement volume is occupied by the glass fibers, the elasticity modulus being calculated as follows: E_theor=E_s.v×(1-V_u.v-V_ep.sv)+E_u.v×(1-V_s.v-V_ep.sv), wherein E_theor is the theoretical value of the elasticity modulus, E_s.v, E_u.v are elasticity moduli of the glass fibers, the carbon fibers and the epoxy binder, respectively; V_s.v, V_u.v, V_ep.sv - the content by volume of the glass fibers, the carbon fibers, and the multicomponent epoxy binder, respectively.

EFFECT: increasing the elasticity modulus and tensile strength of the composite reinforcement, and the possibility of their regulation.
