Title: Innovations by Kris Shigeko Oka
Introduction
Kris Shigeko Oka is an accomplished inventor based in Huntington Beach, CA. He has made significant contributions to the field of materials science, particularly in the development of advanced insulation materials. With a total of 2 patents, Oka's work focuses on innovative solutions that enhance thermal protection systems.
Latest Patents
Oka's latest patents include a hybrid aerogel rigid ceramic fiber insulation and a method of producing the same. This invention features a hybrid insulation material that consists of a porous ceramic substrate material impregnated with nanoporous material. The porous substrate material has a bulk density ranging from 6 to 20 lb/ft and is composed of approximately 60 to 80 wt % silica and 20 to 40 wt % alumina fibers, along with a boron-containing constituent as the sintering agent. The nanoporous material, which has a density ranging from 1.0 to 10 lb/ft, is either fully or partially impregnated into the substrate to block the pores, leading to a significant reduction in conduction via radiation and convection.
Another notable patent is for monazite-based coatings for thermal protection systems. These coatings are designed to stiffen ceramic fabrics without causing embrittlement at temperatures as high as 2400°F. The methods for creating these coatings involve synthesizing high purity monazite and xenotime powders with a stoichiometric ratio of metal to phosphorus of about 1:1.
