Latest Patents
One of Johnston's latest patents is the "Process of making boron-fiber reinforced composite tape." This invention describes an apparatus and method for producing a hybrid boron reinforced polymer matrix composition. The process involves applying boron fibers onto powder pre-impregnated fiber tow bundles, which are then processed through a specialized component. The result is a hybrid boron reinforced polymer matrix composite tape that is collected on a take-up spool.
Another significant patent is the "Dry powder process for preparing uni-tape prepreg from polymer powder." This process involves preparing uni-tape prepreg from polymer powder coated filamentary towpregs. The towpregs are aligned in parallel, and a sandwich material is applied to each side. The sandwich is then heated and subjected to pressure, allowing the polymer to flow and wet the filaments, ultimately forming a uni-tape prepreg that is cooled for further use.
