ABSTRACT:
A method of manufacturing a fluid permeable electrical resistance heater element having a structure that promotes uniformity of flow of fluid through the element and a uniformity of heating throughout the element. The method comprises forming a fluid permeable body of unbonded carbonizable fibres. A latent solvent is applied to the fibres and the solvent is subsequently caused to dissolve at least a surface of the fibres so as to effect bonding of the fibres together. The carbonizable fibres are subsequently carbonized to produce a fluid permeable carbon body.
