Abstract
Natural fiber (such as flax, hemp, jute, kenaf, etc.) reinforced polymer resin composites are biodegradable composites as they are using fibers from renewable sources. It is also better than synthetic fibers (such as glass, carbon, ceramic fibers, etc.) in a sense of environmental cause. In this research work, jute fiber reinforced polypropylene matrix composites have been developed using hot compression molding technique. Various process parameters are used such as fiber condition (untreated and alkali treated), fiber sizes (1, 2 and 4 mm) and percentages (5%, 10% and 15% by weight) in this research work. Tensile test and optical microscopy are used for characterization. Effect of tensile strength has a linear relation with fiber size and fiber percentage but after a certain size and percentage, the tensile strength shows an inverse relation with the fiber length and fiber percentage. There is no significant change has been observed for treated and untreated jute fiber reinforcement.
Highlights
Reason of formation of this voids is the unavailability of materials having high tensile strength with low density and low tensile strength with high density
Jute fiber reinforced polypropylene composites were prepared under various processing parameters using hot compression molding technique
The examination under metallurgical microscope shows the variation of fiber wt. percentages in different jute fiber composites (Figure 1)
Summary
A composite of jute fiber reinforced polypropylene is developed and change of tensile strength is observed. All over the world, it is practiced to develop natural fiber reinforced plastic materials to have greater tensile properties These natural fibers reduced the total cost of materials. Low specific weight, which results in a higher specific strength and stiffness than glass is a benefit especially in parts designed for bending stiffness This is a thermoplastic composite and in case of this composite adhesion between jute fiber reinforcement and polypropylene composite is not so good. Sodium hydroxide increases the interfacial bonding between fiber and matrix In this project, jute fiber reinforced polypropylene composites were prepared under various processing parameters using hot compression molding technique. Optical microscopy was done to show the conditions of fiber with increased fiber loading
