Effect of fibre orientations on the mechanical properties of kenaf–aramid hybrid composites for spall-liner application

TLDR

This paper investigates how kenaf fibre orientation affects the mechanical properties of kenaf–aramid hybrid composites for military vehicle spall liners. Morphological examinations were carried out using scanning electron microscopy. The woven kenaf–aramid hybrid composites exhibited 20.78 % and 43.55 % higher tensile strength, and 19.78 % and 52.07 % higher Charpy impact strength, compared to UD and mat samples, confirming that a woven structure yields superior tensile and impact resistance for spall liner applications.

Abstract

This paper presents the effect of kenaf fibre orientation on the mechanical properties of kenaf–aramid hybrid composites for military vehicle's spall liner application. It was observed that the tensile strength of woven kenaf hybrid composite is almost 20.78% and 43.55% higher than that of UD and mat samples respectively. Charpy impact strength of woven kenaf composites is 19.78% and 52.07% higher than that of UD and mat kenaf hybrid composites respectively. Morphological examinations were carried out using scanning electron microscopy. The results of this study indicate that using kenaf in the form of woven structure could produce a hybrid composite material with high tensile strength and impact resistance properties.
