Latest Patents

One of Raj N Singh's latest patents focuses on a "Silicon carbide composite with metal nitride coated fiber reinforcement." This invention describes a composite material comprised of reinforcement fibers, which are coated with a continuous layer of metal nitride. The permissible metals in the coating include silicon, aluminum, titanium, zirconium, hafnium, niobium, tantalum, and their mixtures. The fibers utilized in this composite are selected from elemental carbon, silicon carbide, and their combinations. The innovative process for forming this composite involves the deposition of a metal nitride coating on the fibers, followed by the admixture with a carbonaceous material, ensuring at least 5 volume percent of the mixture consists of the coated fibers. The resulting preform exhibits an open porosity ranging from about 25 to 90 percent. It is then heated in an inert atmosphere or partial vacuum and infiltrated with molten silicon, leading to the production of an infiltrated composite product.
