Fabrication and Properties of Nanometer Multilayer Compound Heat Insulation Material

Abstract

This research focuses on the development of a nanometer multiple-layer compoundheat insulation material and its preparation procedure. The material consists of alternating layers of an infrared reflecting screen and a spacer. The infrared reflecting screen is made of metal foil or metal plated foil, while the spacer is a thermostability nanometer porous aerogel compoundheat insulation material. The layers are combined using thermostability adhesives or puncturing connection with thermostability sewing threads. The objective of this study is to investigate the properties and preparation procedure of the nanometer multiple-layer compoundheat insulation material. The material offers low density, favorable mechanical properties, and excellent high-temperature heat insulation performance. It reduces the vacuum requirements for vacuum insulation plate core materials and eliminates the need for getters. This material meets the high-efficiency heat insulation requirements of aviation, aerospace, and civil applications. Moreover, the proposed procedure enables the production of large-sized heat insulation material members with complex shapes.
