| Summary: | The post-test deformation and failures of sandwich composites may involve complex interactions between various failure
mechanisms. In this study, the extent of impact damages and response of the thermoplastic honeycomb sandwich are analysed
through energy profile diagrams and associated load history curves. The degree of the postimpact damages of the sandwich is
further characterized using an optical surfaces metrology analysis. The thickness of the honeycomb was found to influence the
extent of the damage which occurred following the low-velocity impact. Thicker core was able to sustain a higher load as well as
the energy absorption before total failure occurred. |
