ABSTRACT:
Handleable and machineable shapes of thermal insulation material are made by compacting finely divided thermal insulation material into the cells of a reinforcing honeycomb structure.
The finely divided thermal insulation material may be, for example, silica aerogel, pyrogenic silica, carbon black, silica gel, volatilized silica, calcium silicate, vermiculite or perlite, or finely divided metal oxides such as alumina or titania. The finely divided thermal insulation material may include an infra-red opacifier and/or reinforcing fibres.
The reinforcing honeycomb structure may be made from, for example, metals such as aluminium foil, inorganic materials such as ceramics, organic materials such as plastics materials, woven fabrics or paper. A rigidiser may be employed.
The shapes of thermal insulation material are substantially rigid and may be machined, for example, by mechanical or laser cutting devices, or may be formed, for example by rolling, into curved or other shaped materials.
