FIELD: technological processes.
SUBSTANCE: present invention relates to impact resistant composites and concerns interlayer toughening to increase of impact resistance of thermoplastic materials. Composite structure contains at least one structural layer of fiber-reinforced thermoplastic resin and at least one toughening layer adjacent to a surface of the structural layer. Toughening layer is configured to create an interlaminar region in a composite laminate and may take the form of a polymer film, a woven or non-woven fibrous material, free particles, a polymer layer or non-woven veil with toughening particles dispersed therein, metal mesh, fiber flakes or particles that are more than 3 micron in size.
EFFECT: invention provides high impact resistance of composite layered material used for in large commercial transport and/or military and aerospace industry, as well as industries that need to use composite materials in difficult conditions.
