Abstract

This research aims to develop a 3D woven honeycomb preform using hemp and Kevlar yarn. Hemp and Kevlar honeycomb preforms with four different cell sizes were developed on a customized weaving machine with multiple beam arrangements. The cell size was varied by changing the number of picks in the free/bonded wall of the honeycomb. The honeycomb composites were developed using the vacuum bagging technique. The quasi-static flatwise compressive strength of the sandwich honeycomb composites was investigated. It was observed that the specific compressive strength of the hemp and Kevlar composite increases with a decrease in cell size. Similarly, the strain energy per unit volume increases with a decrease in cell size. The compressive strength and strain energy per unit volume decrease with an increase in core height.
