ABSTRACT:
The core panel includes a plurality of carbon foam blocks. One or more of the blocks have a cell volume wherein at least about 90% of the cells have a diameter of between at least about 10 microns and about 150 microns. Also at least about 1% of the cell volume of the block has cells having a diameter of about 0.8 microns to about 3.5 microns.
