Flatwise compression behavior of 3D woven honeycomb composites

Lekhani Tripathi et al.

Summary: In this study, 3D woven honeycomb structures were developed with different cell geometry by varying the number of picks in the honeycomb wall. The compression energy absorption of the honeycomb composites was characterized, revealing that regular cell shape, smaller cell size, and a higher number of layers exhibited higher specific energy absorption.

Review: 3D woven honeycomb composites

Lekhani Tripathi et al.

Summary: Honeycomb is an excellent structural material with high strength, shear rigidity, energy absorbing property, low weight, and almost constant crushing force. The hollow spaces in honeycomb structures reduce weight while ensuring required strength. 3D woven honeycomb composites have promising applications as substitutes for aluminum and other metal alloys.
