Heat conducting substrate for electrically heated aerosol delivery device
First Claim
1. An aerosol generating substrate for use in an aerosol source member, said substrate comprising:
- a fibrous filler material;
an aerosol forming material; and
a plurality of heat conducting constituents,wherein the substrate is first formed as a substrate sheet, wherein the heat conducting constituents are part of the substrate sheet, wherein the substrate sheet is subsequently cut into a plurality of pieces, and wherein a collection of intermingled pieces from the plurality of pieces comprises the substrate, and further comprising an overwrap sheet configured to wrap around the substrate, and wherein the overwrap sheet includes a plurality of heat conducting constituents comprising a series of bands formed on the surface of the overwrap sheet.

Abstract
The present disclosure provides aerosol generating substrates and aerosol source members comprising aerosol generating substrates, as well as methods of manufacturing thereof. In an example implementation, an aerosol generating substrate may comprise a fibrous filler material, an aerosol forming material, and a plurality of heat conducting constituents, wherein the substrate is formed as a sheet, and wherein the heat conducting constituents are part of the sheet. The heat conducting constituents may be incorporated within the sheet, or may be formed on a surface of the sheet. In another example implementation, an aerosol source member may comprise a substrate portion formed of a collection of intermingled pieces cut from an aerosol substrate sheet. In addition, or alternatively, a substrate portion may be formed of a series of overlapping layers of an aerosol substrate sheet.
