Reinforced aerogel composite sheet with segmented fiber reinforcement
A recently granted patent (Publication Number: US11931710B2) discloses a reinforced aerogel composite sheet designed for enhanced strength and durability. The composite sheet comprises an aerogel and a segmented reinforcement material sheet with fiber reinforcement. The segmented reinforcement material sheet is characterized by discontinuities across its width, defining segments connected by a face sheet. Notably, the distance between adjacent discontinuities increases along the length of the segmented reinforcement material sheet, contributing to its structural integrity. The fiber reinforcement can be either inorganic or organic, with various materials specified for each category, such as graphite, ceramic, and stainless steel for inorganic fibers, and polycarbonate and polyethylene for organic fibers.
Furthermore, the patent details the composition of the aerogel, which can include a variety of materials such as silica gel, zirconia, alumina, and polyacrylates, among others. Additives like titanium dioxide, iron oxides, and carbon black can be incorporated into the composite sheet to enhance its properties. The patent also describes the thermal conductivity of the reinforced aerogel composite sheet, which is specified to be less than 25 mW/mK at 37.5°C and ambient pressure. Additionally, the patent extends to panels comprising multiple layers of the reinforced aerogel composite sheet, with options for additives and adhesives to further customize the panels for specific applications. The design of the composite sheet and panels aims to provide a versatile and robust solution for various industries requiring high-performance materials.
