| Popis: | Coconut trees are extensively grown in Kerala and Godavari districts and in few locations of Andhra Pradesh. Fibres are extracted from various parts of coconut tree and are exploited by various researchers. In this work an attempt is made to reinforce coconut leaf sheath arbitrarily into polyester matrix. Then the lamina is machined to obtain tensile, flexural and impact test specimens as per ASTM standards. Coconut leaf sheath FRP composites at 12.83%, 11.06% weight fractions have shown tensile strength, modulus of 17.73 MPa, 254.21 MPa respectively. Charpy impact strength of the coconut leaf sheath FRP composites is increased with its content from 1.93 to 5.36 kJ/m 2 . The results from this experimentation have a cleared that the mechanical performance of the composites is increased with number of layers. So, this kind of light weight composite materials may be used for making various parts of automobile. Further the tested specimens are morphologically examined for understanding the interfacial bonding between fibre and polyester resin. Finally the results of present experimentation are compared with other kinds of coconut fibre reinforced polymer composites in order to estimate the better reinforcements. |
