Abstract
This disclosure includes high-temperature, thermally-insulative laminates, Some laminates have a front surface, a back surface, one or more heat-dispersing layers, each comprising at least 90% by weight of: a metal having a melting point of at least 1,300° C. and a thermal conductivity of at least 15 W/Km; or graphite, and one or more heat-insulating layers coupled to the heat-dispersing layer(s), the heat-insulating layer(s) each including a layer of polymeric aerogel, wherein at least a majority of the front surface is defined by one of the heat-dispersing layer(s).
Claims25
