| Abstract: |
| To address the issue of weak bearing capacity of traditional honeycomb cardboard under in-plane compression， a three-layer composite cardboard with a "corrugated-honeycomb-corrugated" structure was innovatively designed and prepared in this study. In-plane quasi-static compression tests were conducted to explore the deformation mechanism of each layer of the composite cardboard. Typical folding units were selected， and based on the corner unit energy dissipation theory， the energy dissipation mechanism of each layer structure was revealed. A theoretical model for the plateau stress of the composite cardboard was established. Comparative tests were carried out on three types of corrugated-honeycomb composite cardboards with different structural parameters. The results showed that the relative error between the theoretical predicted values and the experimental test values ranged from 3.36% to 8.49%. On this basis， the effects of material and structural parameters on the plateau stress was systematically analyzed by using the established theoretical model， and the action mechanism of each parameter was clarified. |
