Title: Innovations by Jonathan Philip Alexander
Introduction
Jonathan Philip Alexander is an accomplished inventor based in Klamath Falls, Oregon. He has made significant contributions to the field of composite materials, holding a total of 3 patents. His work focuses on enhancing the properties of lignocellulosic composites, making them more resistant to moisture and improving their overall performance.
Latest Patents
One of his latest patents is titled "Thin-layer lignocellulose composites having increased resistance to moisture." This invention discloses a method for producing thin-layer lignocellulosic composites, such as wood-based doorskins, that exhibit substantial resistance to moisture. The method involves forming a mixture of refined lignocellulosic fiber, wax, and an organic isocyanate resin. The mixture is pressed to create a loose mat, which is then further pressed between two dies at elevated temperature and pressure. This process promotes the interaction of the resin with the lignocellulosic fibers, resulting in composites that show strong surface strength and high adhesiveness, along with a 50% reduction in linear expansion and thickness swelling in high moisture environments.
Another notable patent is for a "System and method for making extruded, composite material." This invention outlines a method that includes mixing a thermoset polymer, a petroleum distillate, a release agent, and a catalyst to form an admixture. A cellulosic material is then mixed with this admixture to create a generally homogenous furnish. The system comprises a mixing chamber, a feeding chamber, and a die, which includes a pressing chamber with multiple orifices and heating elements.
