Techniques and systems are used to fabricate a thermal protection systems (TPS) for placement on various parts of a structure, such as a spacecraft. The TPS may comprise syntactic foam as a spray-on foam insulation (SOFI), which may be sprayed onto a surface. Alternatively, the TPS may comprise syntactic foam that is applied as preformed panels that are adhered or mechanically attached to a surface. Performance of a syntactic foam may be improved by including an aluminosilicate nanotube material, such as halloysite nanotubes, in a matrix material. The halloysite nanotubes may be hydrated and treated with a silane couplant before being mixed into the matrix material, which may be a two-part silicone based syntactic insulator material, for example. The halloysite nanotubes, in addition to acting as a filler and reinforcement for the syntactic insulator material, release water during oblation, thus contributing to the effectiveness of a TPS.
