Abstract
The flammability characteristics of conventional and advanced composite materials have been extensively studied within the DOD. However, the structural performance of composite materials, the residual strength of composite structures, and the consequences of composite usage on ship sur vivability and damage control during and after fire have not yet been fully assessed.
Residual flexural strength retained (%RSR) after exposure to 25 kW/m2 for a duration of 20 minutes (ASTM E-662) for selected conventional and advanced composite materials is presented. A methodology is presented for the assess ment of the residual strength of composite materials during fire exposure by inter-relationship of mechanical property, temperature, thickness and time.
