Characterization and Properties of Natural Fiber Polymer Composites: A Comprehensive Review

A comprehensive review of techniques for natural fibers as reinforcement in composites: Preparation, processing and characterization.

The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. Natural fibers are sustainable materials which are easily available in nature and have advantages like low-cost, lightweight, renewability, biodegradability and high specific properties. The sustainability of the natural fiber-based composite materials has led to upsurge its applications in various manufacturing sectors. In this paper, we have reviewed the different sources of natural fibers, their properties, modification of natural fibers, the effect of treatments on natural fibers, etc. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials.

Experimental Investigation on Mechanical Properties of Hemp/E-Glass Fabric Reinforced Polyester Hybrid Composites

Ginger is a potential agricultural commodity to be developed in India. When the harvest comes, people still use a very simple method for harvesting ginger by using hoes, pick-axe and other farming equipments. The farmers complain for the need of so many work forces for harvesting while the labor cost is getting increased and the time spent for harvesting process is too long. Although there is an alternative of imported ginger harvesting machines, those machines are not compatible with the farming environment in India, having a high initial and maintenance cost. This machine can be used in any farming condition in India and can be prepared at village level. This machine has three main parts namely, ginger digger, screener and power transmission system. This project is focusing on design and fabrication ginger harvesting machine. The screener will not only separate ginger from soil but also not let the ginger get harmed. The screener also uses for collectible part, to make this machine need some power transmission system from the engine. This machine needs Auto front petrol engine with rotation speed 20 - 25 rpm approximately with the aid of gear reduction.

In this paper, fracture behavior and Mechanical properties of short banana fiber reinforced polymer composites is investigated. Fibers are extracted from banana plant,Further compositelaminates were prepared with randomly distributed fiberswith different weight fraction of banana ranging from 30%, 35% and 40%. Composites are prepared using hand layup technique. Tests were performed to determine fracture toughness (Mode I) and mechanical properties of these laminates. The tests were performed to examine the effect of weight fraction of fiber on the fracture toughness of the composite. As epoxy is a brittle material, stress intensity factor is utilized to evaluate the fracture toughness of the composites. From the experimental results were carried out on different weight fractions of banana. It is observed that the 40 % of banana fiber shows maximum fracture toughness, Composite plate of 30% shows the maximum tensile strength.
