Abstract: A structure comprises at least one layer of thermally conductive, electrically insulating fibers, rovings, strands or yarns having first and second major surfaces, and at least one electrically insulated and/or non-insulated conductive wire or strand woven with the thermally conductive fibers, rovings, strands or yarns so that the electrically insulated and/or non-insulated conductive wire or strand extends from the first major surface to the second major surface in a plurality of locations.
