Method for forming pyrolyzed structures
Abstract
Abstract POROUS, CELLULAR STRUCTURES WHICH HAVE BEEN AT LEAST PARTIALLY CARBONIZED, WHICH HAVE GREATER STRENGTH AT HIGH TEMPERATURES, AND WHICH ARE CAPABLE OF WITHSTANDING HIGHER TEMPERATURES THAN COULD THE STRUCTURES PRIOR TO PYROLYSIS. A METHOD FOR FORMING THE ABOVE STRUCTURES IN WHICH A FIRST BASIC STRUCTURE HAVING A DESIRED CONFIGURATION AND COMPRISES OF MATERIAL HAVING A LOW FUSION OR DETERIORATION TEMPERATURE IS COATED AT EVEN LOWER TEMPERATURES WITH AN INFUSIBLE RESIN WHICH IS CAPABLE OF BEING CURED TO AN INFUSIBLE STATE AT A TEMPERATURE LOWER THAN THE FUSION OR DETERIORATION TEMPERATURE OF THE MATERIAL COMPRISING THE FIRST BASIC STRUCTURE, AND THE RESULTING COATED STRUCTURE, IS THEN SUBJECTED TO ELEVATED TEMPERATURES SO THAT THE BASIC STRUCTURE IS PYROLYZED AND CARBONIZED LEAVING A STRONGER, HIGH-TEMPERATURE-RESISTANT STRUCTURE SUBSTANTIALLY IN THE IMAGE OF THE FIRST BASIC STRUCTURE.
