Title: Innovations of Masayasu Nishihara in Liquid Crystal Resin Technology
Introduction
Masayasu Nishihara is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of liquid crystal resin technology, holding 2 patents that showcase his innovative methods and applications.
Latest Patents
Nishihara's latest patents include a method for preparing a liquid crystal resin composite material. This invention relates to a method for preparing a composite material that comprises a matrix resin of a thermoplastic resin and a liquid crystal resin. The liquid crystal resin has a transition temperature higher than the minimum temperature capable of molding the thermoplastic resin and is formed into a fiber structure as a reinforcing material. The method is characterized by subjecting the composite composition to a melt extrusion process at an apparent shear rate of 3.times.10.sup.2 to 10.sup.5 sec.sup.-1 and above the liquid crystal transition temperature. The resulting material, in filament or thin film form, has fibers of the liquid crystal resin with an aspect ratio of more than 3 in the matrix resin, providing improved tensile strength through a drawing process at a drawing ratio of 11 to 120. Additionally, the composite materials can be subjected to further processes such as gathering, folding, or laminating to form a strand or sheet capable of molding.
Another significant patent is a method for molding a liquid crystal resin sheet and the corresponding molding apparatus. This invention aims to provide a method and apparatus for molding a resin composite sheet with enhanced composite properties. The method includes extruding film sheets through multiple dies from a thermoplastic composite composition and laminating the liquid crystal resin composite films into an integral sheet by superposing and pressing them together at a melt-bonding temperature.
