Abstract:
The socalled ″Xcor sandwich structure″ is a highly promising novel material as an alternative to honeycomb used in aircraft. Although much work has been conducted on the performance of the Xcor sandwich structure, the gap is still hardly bridged between experimental results and theoretical analyses. Therefore, a method has been innovated to establish semiempirical formula for the prediction of compressive and shear moduli of Xcor sandwich structure composites, by combining theoretical analyses and experimental data. In addition, a prediction software was first developed based on the proposed method, of which the accuracy was verified through confirmatory experiments. This software can offer a direct reference or guide for engineers in structural designing.
