Design and Testing of Load Bearing Bushes Using Natural Fibre Composites

Abstract:

Now a day’s bushes are made from nylon and steel. During the production of nylon, the nitrous oxide which is a green-house gas causes global warming. During moulding process shrinkage problem is high in nylon. The primary goal of this study is to develop an environmental friendly bush and to analyze mechanical properties such as tensile, flexural, and impact strength. We can use the natural fibre composites which will be the replacement for nylon bush. We prepared three samples which is of different combinations and different proportion. Sample 1 consists of coconut shell powder (CSP) with epoxy resin, sample 2 consists of neermuli seed powder with epoxy resin and sample 3 consists of CSP, neermuli seed powder with epoxy resins. The samples are prepared by using hand lay-up technique and compression moulding. From the analysis of three samples, sample 3 have good mechanical strength than other two samples. Sample 3 have almost near tensile value (47.77Mpa) to nylon 6 (50 MPa) and have 26% more flexural strength than nylon 6. The cost of the industrial nylon bush is around rupees 65 for 30 x 30 dimensions and the prepared composite for the same dimension cost only 25 rupees and hence the prepared sample 3 is the best replacement for nylon bushes.
