Abstract
A method of making a composite sandwich panel comprises the steps of (i) making a core structure, (ii) making at least one facesheet, (iii) bonding at least one of the at least one facesheets to the core structure, wherein the growth of a carbon nanotube structure is achieved during at least one of steps (i) to (iii).
Claims3
A method of making a composite sandwich panel comprising the steps of
- (i) making a honeycomb core structure comprising cell walls,
- (ii) making at least one facesheet, and
- (iii) bonding at least one of the at least one facesheets to the core structure, wherein growth of a carbon nanotube structure is achieved on a surface of or inside the honeycomb core cell walls during step (i) or step (iii) or after the core structure has been bonded to the at least one facesheet.
