Abstract
A method of manufacturing a fiber reinforced silicone foam is described. An aqueous silicone emulsion that cures upon drying at ambient temperature to an elastomeric film is combined with inorganic fibers having a diameter of less than 25 micrometers and a length of less than 10 mm to form a mixture. Air is dispersed through the mixture to form a stable froth. Removing the water from the stable froth yields an open-cell foam having cell walls comprising a thin layer of silicone elastomer reinforced with fibers. If electrically conductive fibers are used, the foam can be electrically conductive.
