Low density poly(furfuryl alcohol)/clay “PFA/clay” composite aerogels were fabricated by in situ polymerization of aqueous solutions of furfuryl alcohol monomer in the presence of hydrophilic sodium montmorillonite, followed by freeze-drying. Uncured PFA/clay composite aerogels exhibited poor mechanical properties and low water resistance. Oven curing of these materials increased their compressive modului, water resistance, and thermal stabilities. The structures of these PFA/aerogels before and after curing were studied by SEM; their flammabilities were studied by a horizontal burning test and cone calorimetry. Cured aerogels exhibited low flammability, withstanding a gas flame for over 20 s without noticeable combustion.
