Patent ID: 11820872

Abstract:
A method of manufacture of a composite moulding material (1100) comprising a fibrous layer (1102) and a graphene/graphitic dispersion (1104) applied to the fibrous layer (1102) at one or more localised regions (1106) over a surface (1108) of the fibrous layer(1102) in which the graphene/graphitic dispersion (1104) is comprised of graphene nanoplates, graphene oxide nanoplates, reduced graphene oxide nanoplates, bilayer graphene nanoplates, bilayer graphene oxide nanoplates, bilayer reduced graphene oxide nanoplates, few-layer graphene nanoplates, few-layer graphene oxide nanoplates, few-layer reduced graphene oxide nanoplates, graphene/graphite nanoplates of 6 to 14 layers of carbon atoms, graphite flakes with nanoscale dimensions and 40 or less layers of carbon atoms, graphite flakes with nanoscale dimensions and 25 to 30 layers of carbon atoms, graphite flakes with nanoscale dimensions and 25 to 35 layers of carbon atoms, graphite flakes with nanoscale dimensions and 20 to 35 layers of carbon atoms, or graphite flakes with nanoscale dimensions and 20 to 40 layers of carbon atoms, in which the dispersion (1104) is applied to the fibrous layer (1102) using at least one valvejet print head (1112).
