EXPERIMENTAL FIRE PERFORMANCE OF THERMOSET CARBON FIBER EPOXY PANELS UNDER VARIOUS TYPES OF STRUCTURAL LOADING

摘要

The structural response of three types of composite panels under tension, compression,torsion, and no force with an imposed heat flux are examined. The panels decomposed by pyrolysisand oxidative reactions which resulted in flaming and glowing combustion. The current paper focuseson the structural loading response from the test series. Most of the panels incurred distortions causedby relaxation of the imposed loading in response to the combined structural and thermal environment.One panel type did not distort at all under compression and no force, but distorted under tension andtorsion. All panel types were least resistant to forces in torsion. Most panels exhibited minor residualstrength, even after significant heating. The behavior of the three different types of panels wasappreciably different, suggesting that additional work is needed to understand the relevant parametersthat affect structural response in fire-like environments behavior.
