description | Polymer honeycombs, with their light-weight, high stiffness-to-weight ratio, and welldeveloped
energy absorption characteristics, are widely used in engineering applications.
During their application after crushing, the Shape Change Effect (SCE) is observed, in
which the honeycomb bounces slowly back to near its original shape. Previous studies
have seldom focused on the SCE and the factors affecting SCE, such as honeycomb
design shape, loading rate, different polymer materials and second loading. This study
used the 3D printing technology PolyJet to fabricate honeycombs and conducted
compression test and measurements to understand more about the SCE characteristics
and factors affecting SCE in 3D printed honeycombs. Compression tests were carried out
on 3 different shapes of honeycomb, namely hexagon, triangle, and circular, with
different loading rates and different materials DurusWhite and Fullcure720. In the end, 3
stages of SCE were identified and general conclusions on the factors affecting SCE were
reached. |
