Abstract

An analytical procedure is presented which can be used to model the behavior of a polymeric composite panel when subjected to both external loading as well as the high heat flux associated with a fire. The procedure accounts for the elastic and viscoelastic-viscoplastic response, thermal gradients and thermal stresses, and pyrolysis effects. Predictions based on estimated properties for an E-glass/polyester composite panel subjected to a uniaxial tensile load of 250 kN/m (1430 lb/in) and a 1-D heat flux of 10 kW/m2 (22 BTU/hr/in2) are presented. The predicted response is considered to be a reasonable representation of the expected behavior.
