ABSTRACT:
A pipe cladding composition is described which is a phosphate ceramic permeating a non-woven fibrous network. The overall thickness of the sheet is between about 5 and about 20 mils. The phosphate ceramic permeates the fibrous network and extends beyond the fibrous network only up to a maximum thickness of about 3 mils across each side of the sheet. The sheets are prepared using wet reaction mixtures which produce phosphate ceramics. These reaction mixtures are mixed and pressed into the non-woven fibrous network which forms a wet sheet that is then cured to provide the cladding material.
