FIBER REINFORCED COMPOSITE AMORPHOUS HEAT RESISTANT COMPOSITION AND FIBER REINFORCED COMPOSITE HEAT RESISTANT MOLDING

摘要

PROBLEM TO BE SOLVED: To obtain a fiber reinforced composite amorphous heat resistant composition having enhanced elastic-plastic fracture toughness, breaking energy and thermal shock resistance and a fiber reinforced composite heat resistant molding having high strength and excellent in thermal shock resistance. SOLUTION: The fiber reinforced composite amorphous heat resistant composition comprises an aggregate part containing at least SiC and a bonding part reinforced with chops of long SiC fibers having an aspect ratio (length/diameter) of 100-1,000. The fiber reinforced composite heat resistant molding is obtained by molding and drying the composition.
