FIELD: production of composite materials.
SUBSTANCE: invention relates to prepregs, laminar bodies consisting of such prepregs, fiber-reinforced composite materials made from such laminar bodies, and to methods of making such fiber-reinforced composite materials. Permeable laminated body comprises at least one partially impregnated prepreg consisting of component (A) including reinforcing fiber matrix component (B), including thermosetting resin, and, optionally, component (C), which includes a particle or fiber from thermoplastic resin. Invention provides a fiber reinforced composite material with a permeability of at least 4.0×10−14 m2 and void fraction of <1 %.
EFFECT: invention demonstrates ability to be processed during a long period of preparation time and good storage stability.
