Coated reinforcement and method for producing same

A method for producing a coated reinforcement whose surface has a coating of a heat-curable composition, comprising:

• applying to a reinforcement a first mixture comprising at least one resin selected from the group consisting of epoxidized phenol novolaks, epoxidized cresol novolaks, polyepoxides on the basis of bisphenol A, epoxidized fluorenonebisphenols, polyepoxides on the basis of bisphenol F, epoxy resins on the basis of triglycidyl isocyanurates, epoxidized novolaks and combinations thereof, and at least one accelerating component for the curing of the resin;
• subsequently subjecting the reinforcement coated with the first mixture to a heat treatment so that the first mixture is fixed on the surface of the reinforcement by melting;
• thereafter applying a second mixture to the reinforcement coated with the fixed first mixture, wherein the second mixture comprises at least one resin selected from the group consisting of polyepoxides on the basis of bisphenol A or bisphenol F, or on advancement resins prepared therefrom, on the basis of tetraglycidylmethylenediamine, on the basis of epoxidized fluorenonebisphenols, epoxidized novolaks, polyepoxide esters on the basis of phthalic acid, hexahydrophthalic acid or terephthalic acid, epoxidized o- or p-aminophenols, epoxidized polyaddition products of dicyclopentadiene and phenol, and combinations thereof, and at least one anhydride curative or amine curative, to form an assembly, wherein the amine curative is selected from aliphatic polyamines, cycloaliphatic polyamines, aromatic polyamines, polyamides, Mannich bases, polyaminoimidazolines, polyetheramines, and mixtures thereof;
• and
• curing the assembly with heat.
