Latest Patents

One of Boakye's latest patents is titled "Oxidation-resistant fiber coatings and related methods." This invention outlines a method for manufacturing a coated reinforcing fiber intended for use in Ceramic Matrix Composites. The process involves pre-oxidizing silicon-based fibers at temperatures ranging from 700 to 1300 degrees Celsius in an oxidizing atmosphere to create a silica surface layer. Following this, a rare earth orthophosphate (REPO) coating is applied, and the fibers are heated in an inert atmosphere to form 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 from about 5 minutes to about 100 hours.

Another significant patent is focused on "Coating ceramic fiber tows and woven articles." This improved method for coating ceramic fibers involves thoroughly wetting the fibers with precursors in a solution before they react to form a coating through heterogeneous nucleation and growth. The fibers are then rinsed and fired, with the option to repeat the process in stages to increase coating thickness. This flexible method is beneficial for both batch and continuous operations, effectively reducing the cost and time required to produce ceramic matrix composites.
