FIELD: polymer production.
SUBSTANCE: compositions used to obtain a sizing coating of structural fibers. An epoxy-silane composition is proposed for finishing structural fibers of polymer composite materials based on thermoplastic binders, containing from 90 to 55 wt.% of the epoxy component and from 10 to 45 wt.% of organosilane, in the structural formula of which there are amine and hydrolysable groups.
EFFECT: increase in the surface energy of the fiber coated with the claimed sizing epoxy-silane composition, at low values of the surface energy of the composition before it is applied to the fiber.
