Title: Innovations by Kenneth S. Yao
Introduction
Kenneth S. Yao is an accomplished inventor based in San Gabriel, California. He has made significant contributions to the field of composite materials, particularly in the manufacture of flat surfaced composites. With a total of 2 patents, his work focuses on enhancing the properties and applications of polymer matrices filled with powdered materials.
Latest Patents
Kenneth S. Yao's latest patents include innovative methods for the manufacture of flat surfaced composites comprising powdered fillers in a polymer matrix. His first patent describes a process where composite materials, which are highly filled with about 60 to 70 volume percent of finely powdered filler material, are created by dissolving the polymer in a volatilisable solvent. This mixture is then subjected to high shear mixing to ensure homogeneity. The solvent is subsequently removed while maintaining the mixture's uniformity, followed by the extrusion of an extremely thin film or tape. The remaining solvent is eliminated through heating, ensuring no significant non-uniformity occurs. The final product is formed by stacking thin coherent layers and pressing them in a mold, allowing the melted polymer to unite the layers and fill the spaces between the filler particles.
His second patent also focuses on highly filled composite materials, which contain approximately 60 volume percent or greater of finely powdered filler in a polymer matrix. The process involves dissolving the polymer in a volatilisable solvent, adding the filler, and forming a homogeneous mixture through high shear mixing. Similar to his first patent, most of the solvent is removed while maintaining homogeneity, followed by the extrusion of a thin layer of the composite material. The bodies formed from this dried layer are then heated and pressed to melt and disperse the polymer into the interstices between the filler particles. This innovation allows certain polymers, which are ineffective at low solids contents, to become effective bonding materials at high solids contents.
