Fiber reinforced polymer composite structures have valuable characteristics for its use in marine and off‐shore applications. On the other hand, a potential problem with these structures is their behavior in the presence of fire. Most polymer matrix systems soften when the glass transition temperature is approached, and decompose at higher temperatures. The present paper describes preliminary research addressed to determine the behavior of water filled composite pipes under the effect of high temperatures. Approximate procedures are reviewed for the determination of the temperature‐time history and the corresponding decrement in strength. Then, an alternative procedure using thermal and viscoelastic numerical analyses is proposed.
