Summary
Composite foams have been prepared which incorporate the best attributes of two materials. Polystyrene emulsion foams have the advantages that they can be prepared easily over a wide range of densities (.015 g/cc to 0.20 g/cc) and are easy to handle and machine; however, the small cell sizes needed for good wicking of the DT liquid fuel are difficult to achieve. On the other hand, Si aerogel and resole foams have the desired small cell size (<0.1 ..mu..m), but the materials are mechanically weak making them difficult to handle and machine. Using a backfilling process, we have been able to make binary composite foams in which the cells of the polystyrene emulsion foam have been filled with aerogel or resole foam. These materials have the small cell sizes needed for good wicking of the liquid DT fuel and are rugged and easy to machine. 3 refs., 8 figs.
