Abstract
The energy absorption characteristics of continuous fibre reinforced laminated plates made from three material systems: APC-2 (graphite/PEEK), AS4/3502 (graphite/epoxy), and a hybrid AS4/Kevlar-49/3502 composite, have been investigated. The effects of geometric scaling of specimen size, ply-level and sublaminate-level scaling of the stacking sequence, and trigger mechanism on the energy absorption capability in edgewise compression were evaluated. Scaling method and matrix material were found to influence the preferred crushing mode and energy absorption efficiency of the composite plates. Energy absorption and crushing modes where found to be similar to that of composite tubes.
