NATURAL COMPOSITE MATERIAL USING MUSA PARADISIACA PSEUDO STEM V.RAJIVE Assistant professor, Dept of Mechanical Engineering, Apollo College of engineering, Chennai, Tamil Nadu ,India ---------------------------------------------------------------------***---------------------------------------------------------------------
Abstract - : Natural fiber composite is obtained from nature
in the form of leaf, seeds, tree, fruit wastage from these parts are used for manufacture of composite materials to deliberately combined to from heterogeneous structures with desired properties .This is also called as reinforced polymer composite materials. Guard rails are easily manufacture using Natural fiber composite. Before scientists have created many natural fibers from different materials, they also determined physical properties of these composite materials. This composite materials in continuous of above I have create the composite material using the fiber of Musa paradisica and I have found the characterizes like(tensile strength, hardness, water aberration ,and flexural rigidity)of the composite materials this materials find usage in the manufacture of play wood, automobile body, construction board, insulation board ,flooring and manufacturing of chair and seat etc .This Musa paradisicaisin abundant is available it is weight less material, and has desired strength, low specific gravity.
Key Words: Natural fiber (Musa paradisiaca) ,Epoxy resin ,Hardener, Patterns.
1. INTRODUCTION 1.1. Overview of Composites Over the last three decades composite materials, plastics and ceramics have been emerging as dominant materials. The volume and number of application of composite materials have grown steadily, penetrating and conquering new markets relentlessly. The efforts to produce economically attractive composite components have resulted in several innovative manufacturing techniques currently being used in the composite industry. It is obvious, especially for composites, that the improvement in manufacturing technology alone is not enough to overcome the cost hurdle. It is essentially that there is an integrated effort in design, materials, process, tooling, quality assurance, manufacturing and even program management for composites to become competitive with metals. The composites industry has been begun to recognize that the commercial applications of composites promise to offer much larger business opportunities than the aerospace sector due to the sheer size of transportation industry. For certain applications, the use of composites rather than metals has in fact resulted in savings of both cost and weight. Some examples are cascades for engines, curved fairing and fillets, replacement for welded metallic parts, Š 2017, IRJET

cylinders, tubes, ducts, blade containment bands etc. Composites are now extensively being used for rehabilitation strengthening of pre-existing structures that have to be retrofitted to make them seismic resistant, or to repair damage caused by seismic activity. Unlike conventional materials (eg. Steel), the properties of the composite material can be designed considering the structural aspects. The design of a structural component using composites involves both material and structural design.
1.2. Hybrid Composite Materials Hybrid composite are more advanced composites as compared to conventional FRP composites. Hybrid can have more than one reinforcing phase or a single reinforcing phase with multiple matrix phases. They have better flexibility as compared to other fiber reinforced composites. Normally it contains a high modulus fiber with a low modulus fiber. The high modulus fiber provides the stiffness and load bearing qualities, whereas the low modulus fiber makes the composite material more damage tolerant and keeps the material cost low. The mechanical properties of a hybrid composite can be varied by changing volume ratio and stacking sequence in different plies. There are several types of hybrid composites characterized as follows. 1. Interplay or Tow-by-Tow, in which tows of the two or more constituent types of fiber are mixed in a regular or random manner. 2. Sandwich hybrids, also known as core shell in which one material is sandwich between two layer of another. 3. Interplay or laminated, where alternate layers of the two or more materials are stacked in a regular manner.
1.3. Fiber Reinforcement Common fiber reinforcing agents include asbestos, carbon / graphite fibers, beryllium carbide, beryllium oxide, molybdenum, aluminum oxide, glass fibers, polyamide, natural fibers etc. similarly common matrix materials include epoxy, phenolic, polyester, polyurethane, poly etherether ketone (PEEK), vinyl Ester etc. Among these resin materials, PEEK is most widely used.
