NANOINDENTATION MEASUREMENTS OF JUTE/POLY LACTIC ACID COMPOSITES
Original language description
The performance of natural fiber reinforced polymer composites depends on the quality of stress transfer in the interphase between fiber and polymer in the composite. However, due to the difficulty in measurement of mechanical properties at interphase, the composites show uncertain trend in improvement of performance. The purpose of this study was to measure the mechanical properties of the interphase using nanoindentation technique. In the present study, 3 wt % of jute fibers of millimeter, micrometerand nanometer scales were incorporated in poly lactic acid (PLA) matrix to prepare composite films by solvent casting. The reinforcement potentials of fibers at different sizes from millimeter to nanometer were investigated from the improvements in elastic modulus of composite films based on nanoindentation measurements. The increase in elastic modulus was observed by 65.21 %, 25.40 % and 13.04% for composite films of nanofibers, microfibers and milifibers respectively compared to neat P
