Abstract
The time-temperature dependent flexural strength of honeycomb sandwich (SW) composite panel with Nomex^<TM> honeycomb core and satin-woven glass fiber/epoxy face sheets was studied as well as glass fiber reinforced plastic (GFRP) laminate of face sheet. The three-point bending with constant strain rate (CSR) was employed. The experiment results show that the SW panel indicates time-temperature dependent behavior. Relevant experiments of dynamic test and CSR flexural test of GFRP laminate of face sheet were performed and compared, the time-temperature characteristics are consistent. Failure mechanism of SW panel was analyzed by fractograph and FEM analysis.
