In one aspect, an aerosol delivery device may comprise a control body having a closed distal end and an open engaging end, a heating member, a control component located within the control body and configured to control the heating member, a power source located within the control body and configured to provide power to the control component, and a removable aerosol source member that includes a substrate portion. The substrate portion may include a continuous heat conductive framework integrated with an aerosol forming material, wherein the continuous thermally conductive framework is configured to enhance heat transfer from the heating member to the aerosol forming material. ## Claims ### Claim 1 An aerosol delivery device configured to yield an inhalable substance, the aerosol delivery device comprising: a control body having a closed distal end and an open engaging end; a heating member; a control component located within the control body and configured to control the heating member; a power source located within the control body and configured to provide power to the control component; and a removable aerosol source member that includes a substrate portion, the aerosol source member being configured to be inserted into the engaging end of the control body and defining a heated end and a mouth end, the heated end configured, when inserted into the control body, to be positioned proximate the heating member, and the mouth end configured to extend beyond the engaging end of the control body, wherein the substrate portion includes a continuous thermally conductive framework integrated with an aerosol forming material, wherein the continuous thermally conductive framework is configured to enhance heat transfer from the heating member to the aerosol forming material, and wherein the continuous thermally conductive framework comprises an interwoven or overlapping braid, and wherein the interwoven or overlapping braid comprises individual strands that intersect or overlap each other at a non-zero angles therefrom. ### Claim 2 (depends on 1) The aerosol delivery device of claim 1, wherein the interwoven or overlapping braid is disposed about an outer surface of the aerosol forming material. ### Claim 3 (depends on 1) The aerosol delivery device of claim 1, wherein the interwoven or overlapping braid is disposed within the aerosol forming material. ### Claim 4 (depends on 1) The aerosol delivery device of claim 1, wherein the continuous thermally conductive framework comprises at least one of a metal material, a coated metal material, a ceramic material, a carbon material, a polymer composite, and any combination thereof. ### Claim 5 (depends on 1) The aerosol delivery device of claim 1, wherein the substrate portion comprises an extruded hollow structure. ### Claim 6 (depends on 1) The aerosol delivery device of claim 1, wherein the substrate portion comprises a single centrally located longitudinal hole and/or a plurality of longitudinal holes. ### Claim 7 (depends on 1) The aerosol delivery device of claim 1, wherein the substrate portion comprises a substantially solid structure. ### Claim 8 (depends on 1) The aerosol delivery device of claim 1, wherein the substrate portion comprises a tobacco or a tobacco-derived material. ### Claim 9 (depends on 1) The aerosol delivery device of claim 1, wherein the substrate portion comprises a non-tobacco material. ### Claim 10 (depends on 1) The aerosol delivery device of claim 1, wherein the heating member comprises an inductive heat source. ### Claim 11 An aerosol source member configured to removably engage an engaging end of a control body that includes a heating member, the aerosol source member comprising: a heated end and a mouth end, the heated end configured, when inserted into the control body, to be positioned proximate the heating member, and the mouth end configured to extend beyond the engaging end of the control body; and a substrate portion that includes a continuous thermally conductive framework integrated with an aerosol forming material, wherein the continuous thermally conductive framework is configured to enhance heat transfer from the heating member to the aerosol forming material, and wherein the continuous thermally conductive framework comprises an interwoven or overlapping braid, and wherein the interwoven or overlapping braid comprises individual strands that intersect or overlap each other at a non-zero angles therefrom. ### Claim 12 (depends on 11) The aerosol source member of claim 11, wherein the interwoven or overlapping braid is disposed about an outer surface of the aerosol forming material. ### Claim 13 (depends on 11) The aerosol source member of claim 11, wherein the interwoven or overlapping braid is disposed within the aerosol forming material. ### Claim 14 (depends on 11) The aerosol source member of claim 11, wherein the continuous thermally conductive framework comprises at least one of a metal material, a coated metal material, a ceramic material, a carbon material, a polymer composite, and any combination thereof. ### Claim 15 (depends on 11) The aerosol source member of claim 11, wherein the substrate portion comprises an extruded hollow structure. ### Claim 16 (depends on 11) The aerosol source member of claim 11, wherein the substrate portion comprises a single centrally located longitudinal hole and/or a plurality of longitudinal holes. ### Claim 17 (depends on 11) The aerosol source member of claim 11, wherein the substrate portion comprises a substantially solid structure. ### Claim 18 (depends on 11) The aerosol source member of claim 11, wherein the substrate portion comprises a tobacco or a tobacco-derived material. ### Claim 19 (depends on 11) The aerosol source member of claim 11, wherein the substrate portion comprises a non-tobacco material. ### Claim 20 (depends on 11) The aerosol source member of claim 11, wherein the aerosol source member is configured to be heated via induction heating.
