Studies Onmechanical Properties of Nano –Hemp Fibre Composite Material
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 10
Abstract
The use of natural fibers instead of traditional reinforcement materials such as glass fibers, carbon provides several advantages including low density, low cost, good specific mechanical properties, and biodegradability. Due to low prices, eco-friendly and high tensile behaviour leads to rising commercial performance of natural fibre reinforced plastics in all around the world. The primary aim of this research work was to investigate the mechanical properties of green composites reinforced with raw hemp and nano-hemp fibre. Many research report shows that the nano fibre reinforced structures exhibit higher mechanical properties. Initially the raw hemp fibre was broken down in to sub-micron fibrillar structure and subsequently to the level of nanofibril through physico-chemical methods where in a mild chemical treatment was given to separate the foreign particles such as pectin, wax and lignin. Further to this stage mechanical defibrillation has done through commercial grinder to isolate nano fibres from raw hemp. Theaverage diameters of the generated nanofibres in the range of 20-100nm and the generated nano fibres have higher crystallinityas compare with the raw fibre bundles due to the removal of hemicellulose. Nano fibres of hemp were characterized by FE-SEM and crystallinity of raw hemp structure andnano fibril based hemp structures were studied through X Ray Diffraction. The nano fibre was reinforced with Epoxy matrix to produce the composite structure with various fibre volume fraction such as 2%,4%,6%,8% and 10% ,similarly the raw hemp fibre was used to produce the same structures through hand layup technique. The mechanical properties of composites made from raw hemp fibre as well as nano hemp fibre were studied. The nano hemp fibre reinforced composites shows higher performance properties as compare with raw fibre based composites.
