Nanoparticle modification of epoxy matrix systems for advanced (carbon) fibre reinforced polymer (CFRP) components offers promising potential for enhanced service lifetime and improved material properties like electrical conductivity. In contrast to well examined carbon nanotube (CNT) modifications, graphene modified resins offers the potential for liquid infusion processes such as resin infusion or vacuum assisted resin transfer moulding (VARTM) due to nearly unaltered viscosity. In this study we present the impact of graphene modification on fracture toughness of a standard industrial epoxy resin. Starting with the basic characterization of the formed nanocomposites, the transfer to VARTM manufactured CFRP laminates and their compression after impact properties is examined. CFRP coupons were subjected to impact damage and subsequently loaded under compressive load.
