A method of forming a heat shield that involves thermally stabilizing a plurality of phenolic microspheres; mixing the thermally stabilized phenolic microspheres with a phenolic resin to form a phenolic ablative material; compressing the phenolic ablative material into a honeycomb core; and allowing the phenolic ablative material to cure.

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.
