An Experimental Study on Hemp/Sisal Fiber Embedded Hybrid Polymer Composites

Abstract: Environmental concerns encourage the use of artless fibers since bio-fiber embedded polymer composite crumble easily in nature and cheaper compare to petroleum-based fibers. Cellulosic fibers are gradually more gaining attention as their uses are diversified into structural and automobile parts for vehicle where low weight is necessary. The low density of cellulosic fibers is very beneficial in the structural and automobile industry. Cellulosic fibers offer many ecological and technical benefits for its use in incorporating composites. Current research paper investigates the mechanical strength (tensile, flexural, compression strength and shore-D hardness) and water absorption performance of different weight percentage of hemp/sisal fiber embedded polymer resin (epoxy resin) hybrid composites. Hemp and sisal fiber surfaces were subjected to 10 weight percentage of alkaline (NaOH) solution to improve the bonding characteristic between hydrophilic cellulosic fibers and hydrophobic polymer resin. Hybrid composite specimens were prepared by simple cold pressing technique. A 40 weight percentage of hemp/sisal fiber embedded hybrid composite sample discloses maximum tensile strength, flexural strength and compression strength. Shore-D hardness value and absorption of moisture of hybrid composite samples increases with increase in fiber loading. Morphological analyses are carried out to analyze the fractured surface of hybrid composite samples by using scanning electron microscope (SEM) and reported. The investigational result also discloses that the hemp and sisal fibers are promising reinforcements for use in cheaper bio-composites which have high strength to weight ratio.

An Experimental Study of Static and Dynamic Behavior of the Hybrid Composite

Abstract: ABSTRACT Hybrid composites containing natural fibers are widely used for various applications due to their superior mechanical properties over synthetic fibers. The mechanical behavior of such hybrid composites under dynamic loading is a key concern. In the present study, a six-layered hybrid composite fabricated with four different layers of natural (sisal, flax, jute, and hemp) fibers, with top and bottom layers of synthetic glass fiber, is investigated for the impact strength and strain rate effects. The fractography at different strain rates has been analyzed using scanning electron microscopy. From the investigation, it is found that the strength bearing capacity of the hybrid composite increases as the strain rate is increased from 0.00022 s−1 to 0.0888 s−1. It is observed that there is an enhancement of 8.21% in the tensile strength, with average hardness and impact energy, which are 48.5 HV and 8 J, respectively. It is concluded that the developed composite is suitable for high strain rate applications.
