Latest Patents

Randal S Hay holds a patent for "Oxidation-resistant fiber coatings and related methods." This patent describes a method of manufacturing a coated reinforcing fiber for use in Ceramic Matrix Composites. The process involves pre-oxidizing silicon-based fibers at temperatures between 700 to 1300 degrees Celsius in an oxidizing atmosphere. This step forms a silica surface layer on the fibers. Following this, a rare earth orthophosphate (REPO) coating is applied, and the fibers are heated in an inert atmosphere to create a rare earth silicate or disilicate. The pre-oxidizing step can last from 0.5 hours to about 100 hours, while the heating step may take about 5 minutes to about 100 hours. Randal S Hay has 1 patent to his name.
