An apparatus comprises a containment chamber, a foam inlet, a vacuum port, and an air inlet. The containment chamber is a walled structure having a foam inlet. The surrounding of the foam inlet is shaped to correspond to the internal dimensions or surface structure of an aircraft fuselage or other aerospace structure. Because the surrounding of the foam inlet corresponds to the shape of the insulated structure, the containment apparatus may be mated with the portion of the structure having the insulation removed or captured. The vacuum port of the apparatus is connectable to a vacuum source, and the apparatus is utilized to suction particulate foam material from the insulated structure.

A highly abrasion resistant and durable, low density ablator composition is provided that comprises a base silicone resin, silica microballoons as a filler, a catalyst, and a thinning fluid to control the viscosity of the base silicone resin. The density of the resulting composition is approximately 0.32 g/cc yet the composition has excellent abrasion resistance. Furthermore, the ratio of filler to base silicone resin, by weight, is approximately 0.91. The ablator composition is also RF (radio frequency) transparent, moisture resistant, and low cost. Methods of mixing the ablator composition and forming ablative structures are also provided.
