Patent number: 10843812Abstract: Components having fibre-reinforced composite structures are disclosed. The component comprises a plurality of structural fibres embedded in a cured matrix material and a plurality of nanostructures such as carbon nanotubes extending from one or more of the structural fibres. In some embodiments a density of the nanostructures is at least 107 nanostructures per cm2 of surface area of the one or more structural fibres. In some embodiments, the nanostructures extend from an outer fibre proximal to an outer surface of the component but not from an inner fibre distal from the outer surface. In some embodiments the one or more structural fibres from which the nanostructures extend are free of a sizing agent.Type: GrantFiled: December 8, 2015Date of Patent: November 24, 2020Assignees: SHORT BROTHERS PLC, UNIVERSITY OF SURREYInventors: Paolo Ballocchi, Philip Jenkins, Ian Hamerton, Ravi Silva, Thomas Pozegic
