Mechanical properties of Nomex honeycomb sandwich panels under dynamic impact
Source abstract
Abstract
Abstract Through experiments and numerical simulation, the dynamic mechanical behaviors and mechanical properties of Nomex honeycomb sandwich panels under impact loads were investigated. On this basis, the effects of the density of honeycomb cores, face-sheet thickness, punch diameter, and impact energy on impact loads and failure modes were explored. The predicted contact time, impact load, and failure mode were consistent with the test results. Results showed that face-sheet thickness exhibited an extremely significant influence on the impact resistance of Nomex honeycomb sandwich panels; the density of honeycomb cores exerted a certain effect on the structural stiffness; the punch diameter and impact energy also influenced the mechanical properties and failure modes of sandwich panels.
