Publication number: 20210355331Abstract: This invention relates to coating compositions for thermal protection of substrates (particularly for protecting surfaces that are subject to transient, extreme temperature excursions), processes for manufacturing the coating and methods for applying them. The coating is designed to reduce/minimize the thermal diffusivity of the composite and uses constituent materials selected from groups of inorganic fibers, hollow microspheres, aerogels, and inorganic binders. Thermal diffusivity can be reduced/minimized by controlling the relative concentrations of the coating components.Type: ApplicationFiled: February 8, 2021Publication date: November 18, 2021Applicant: Ocellus, Inc.Inventors: Michael Droege, Shannon Downey, Lawrence Hrubesh

Patent number: 6770584Abstract: A hybrid insulation material comprises of porous ceramic substrate material impregnated with nanoporous material and method of making the same is the topic of this invention. The porous substrate material has bulk density ranging from 6 to 20 lb/ft3 and is composed of about 60 to 80 wt % silica (SiO2) 20 to 40 wt % alumina (Al2O3) fibers, and with about 0.1 to 1.0 wt % boron-containing constituent as the sintering agent. The nanoporous material has density ranging from 1.0 to 10 lb/ft3 and is either fully or partially impregnated into the substrate to block the pores, resulting in substantial reduction in conduction via radiation and convention. The nanoporous material used to impregnate the fiber substrate is preferably formed from a precursor of alkoxysilane, alcohol, water, and an acid or base catalyst for silica aerogels, and from a precursor of aluminum alkoxide, alcohol, water, and an acid or base catalyst for alumina aerogels.Type: GrantFiled: August 16, 2002Date of Patent: August 3, 2004Assignee: The Boeing CompanyInventors: Andrea O.
