PREPREG AND ARTICLE MADE OF THE SAME Russian patent published in 2006 - IPC B32B27/38 C08J5/24 C08L63/00 C09J163/00 C08K3/04 C07C211/01 

FIELD: structural materials for airspace industry.

SUBSTANCE: claimed prepreg contains 24-50 mass % of polymer binder and 50-76 mass % of fibrous filler. As fibrous filler carbon, organic, glass bundles, fabrics and strips are used. Polymer binder contains (mass pts): N,N,N'N'-tentraglycidyldiamino-3,3'-dichlorodiphenyl methane as epoxy oligomere 100; 4,4'-diaminediphenyl sulfone as curing agent 44; fullerene C_2n, wherein n >= 30, 0.01-1.0; opened carbon nanotubes 0.1-1.5; fulleroidal multilayered nanomodifier 0.5-10, and fullerene amino derivative of general formula C₆₀(GA)₆. Said amino derivative represents reaction product of fullerene C₆₀ with hepthylamine (GA). Article from prepreg is obtained by extrusion.

EFFECT: prepreg with decreased flowability and gel-forming time; composites of increased degradation energy and rest compressive strength.
