Effect of fiber stacking sequence and orientation on quasi- static indentation properties of sustainable hybrid carbon/ramie fiber epoxy composites

Hybrid polymer composites reinforced with synthetic and natural fibers are gaining more interest in current composite technology an effort to promote sustainability without sacrificing the performance of fiber composites. The goal this study is see how stacking sequence carbon ramie fiber, as well orientation affects quasi-static indentation behaviour carbon/ramie epoxy hybrid specimens were made using a hand layup approach followed by hot pressing process. properties reinforcements matrix investigated hemispherical indenter at varying displacement rates 10, 20, 30 ?mm/min for stated orientation. resistance qualities evaluated terms force, specimen energy absorption capability, damage caused penetration. results reveal that 5 layers has better capabilities, absorbing 114.926 ?J 20 rate. Similarly, force increases number increases. These indicate have great potential towards low velocity impact applications.
