Title: Molten salt destruction of composite materials
Inventor: SCHNITTGRUND GARY D
IPC: F23G7/00
Filed: 1995-01-23
Abstract: A process for destruction of composite materials capable of oxidation in a molten salt such as graphite fiber reinforced epoxy materials, comprising introducing such composite materials into a molten salt bath, e.g. molten sodium carbonate, at elevated temperature, e.g. between about 900 and 1000°C, together with air or oxygen, and catalytically oxidizing and destroying the composite material and recovering an off-gas containing chiefly CO2. When employing composites containing ceramic material such as silicon, as for example silicon carbide fiber reinforced carbon matrix, the silicon is converted to a silicate as a spent salt retained in the molten salt bath, while the carbon is converted to CO2.
