Mixed-mode II + III delamination behaviour of flax / epoxy laminated composite

Abstract

This research describes delamination of flax/epoxy composite under mixedmode I + III. The aim of this research is to study behavior mixed mode I+III delamination of flax / epoxy laminated composite. The experiment eight-point bending plate (8PBP) test was selected to study the delamination behavior flax/epoxy composite under mixed-mode I+III. The specimen flax/epoxy composite was fabricated use staking method with manual hand lay-up and curing process by vacuum bagging at room temperature. The specimen flax/epoxy composite was tested in room temperature. During test, it was observed that the delamination propagates increase before peak load. The maximum load obtained from these test has been analyzed and compared with data available from published source. Result indicated that the force against displacement graph characteristic produced by flax/epoxy composite have similarity with published data. Therefore the objective of this experiment 8PBP mixed mode I+III delamination has been successfully conducted and proven with published experimental data.
