Influence of fumed silica nanofiller and stacking sequence on interlaminar fracture behaviour of bidirectional jute-kevlar hybrid nanocomposite

Influence of fumed silica nanofiller and stacking sequence on interlaminar fracture behaviour of bidirectional jute-kevlar hybrid nanocomposite

The present study aims to examine the influence of nanofiller content and stacking sequence on the interlaminar fracture properties of Jute-Kevlar hybrid nanocomposite. Mode I and Mode II interlaminar fracture properties are characterized by double cantilever beam (DCB) and end notch flexure (ENF) t...
