ABSTRACT:
A fireproof barrier system for a composite structure is provided. A sheet ablative material is bonded onto the composite structure to be fireproofed. A protective phenolic resin skin is deposited on the sheet to protect the ablative material from handling and water damage while further improving the fire performance of the system. The protective skin may have between about 50 to 80 parts per hundred of aluminum trihydrate mixed therein. The protective phenolic resin skin may further be glass-reinforced.
