摘要： The present invention provides
a process for manufacturing gel sheets, comprising the steps of:
providing a quantity of fibrous batting material;
introducing a quantity for an impermeable material to separate the quanttiy of fibrous batting material and rolling into a fiber-roll preform having a plurality of fibrous layers;
infusing a quantity of catalyzed sol into the fiber-roll preform; and gelling the catalyzed sol in the fiber-roll preform to form a gel sheet roll. Such gel sheets are used in manufacturing aerogel blankets used in a variety of applications including thermal and acoustic insulation.
