Fibrous sheet composites are prepared by (a) forming an aqueous dispersion comprising asbestiform crystalline calcium M phosphate fibers wherein M is a metal cation selected from the group consisting of sodium and lithium, and mixtures thereof, auxiliary fibers, and a water insoluble organic polymeric binder; (b) distributing and draining the aqueous dispersion on a porous substrate to form a wet sheet-like solid phase or wet web; and (c) pressing and drying the wet web.

Process for preparing sheet composites containing crystalline phosphate

Sheet composites containing asbestiform crystalline calcium M phosphate fibers wherein M is a metal cation selected from the group consisting of sodium and lithium, and mixtures thereof, are useful as a replacement or substitute for asbestos sheets in applications where fibrous materials are needed.

Sheet composites containing crystalline phosphate fibers

Composites possessing desirable properties are produced from compositions comprising molten elemental sulfur and crystalline phosphate fibers. These composites are useful for the fabrication of various structures, such as tanks, pipes, sheeting, pavement surfaces and the like.
