Abstract:
A method for producing a ceramic network from a fiber network comprising fiber selected from polymer fiber, natural fiber or mixtures thereof comprising:impregnating the fiber network with a ceramic suspension, removing excess ceramic suspension from the impregnated fiber network, drying the impregnated fiber network, removing the fiber network, and sintering the remaining network to form the ceramic network, wherein the fiber has a cross-sectional area having a circular, a substantially circular, a convex or a multiply convex outline, the ceramic network comprising struts including cavities having a cross-sectional area with a circular, substantially circular, a convex, or multiply convex outline, said struts being joined together two-dimensionally or three dimensionally, having a material-consistent connection to one another and having an interconnected cavity over their points of contact.
