“…Modern out-of-autoclave technologies for the preparation of composites, such as pressure impregnation, infusion, impregnation by film binders, etc., require the development of binders adjusted for their specifics [26,36,43]. One of the principal demands of these technologies is that the viscosity of the binder should be low to ensure efficient impregnation of the filler.…”

“…A summary table of various modification methods was presented in review [24]. These methods include the formation of IPNs [25,26] and the introduction of nanoparticles of various chemical natures and morphologies (specifically, carbon nanotubes) [27,28]. A promising strategy consists in the use of hyperbranched polymers: Functionalized (with terminal hydroxyl or epoxy groups) polyesters are usually used for this purpose.…”

Main methods for the modification of epoxy composites that aim to increase their impact and crack resistances are considered with the main attention focused on modification with the use of thermally stable thermoplastics as additives. The influence of various factors (the modifier-matrix chemical bond and the morphology and molecular weight of the modifier) on the physicomechanical characteristics of the composites is discussed. New approaches to the toughening of polymeric composite materials based on epoxy thermosets that involve the use of modified binders or the introduction of a modifier between layers of the composite prepreg are advanced.
