摘要
Abstract
A new kind of MLIMs are prepared,whose spacer is made from Al2O3 fiber mat,and silica aerogels is implanted on the surface of Al2O3 fiber through Sol-Gel process.In high vacuum(10-3 Pa),the effective thermal conductivity of the new MILMs could be reduced by 21.8％,at the same time,the weight could be reduced by 67.2％.Furthermore,this MLIMs shows good insulation performance in high temperature of 1200 K and low vacuum(100 Pa).关键词
