Abstract
An ablative fibrous ceramic article comprises a honeycomb core having a plurality of cells, fibrous ceramic insulation (including fibers, microballoons, microparticles, or mixtures thereof) at least partially filling each cell of the core and forming a porous sheet on one face of the core, and, optionally, an ablative material infused into a portion of the porous sheet. Such an article is a candidate for fabricating an effective lunar/Martian aerobrake.
