Abstract: The thermal
aging of silica alcogels in an alcohol solution is an important step in the production
of fiber reinforced aerogel insulation. However, aging is time consuming and process
limitations at the manufacturing scale are not well understood. Two approaches have been
taken to develop a better understanding of aging with the goal of process acceleration.
First, the thermal ... read moreconductivity of fiber reinforced silica alcogel has been measured as
a function of aging time using the transient line-source technique and property change
has been considered as a means of process monitoring. Alcogel thermal conductivity was
found to be 0.25 Wm−1K−1
