Abstract

• In the present work, Taguchi method; a Design of Experiment (DOE) technique was used to optimize the process parameters to prepare the areca nut fibre - natural rubber composite possessing desired qualities, using minimum of time and resources. The tools and techniques such as, orthogonal array, signal-to-noise ratio (S/N), and the optimum condition were employed in Taguchi method to study the process parameters of the areca nut fibre - natural rubber composite. Three factors, namely fibre treatment type, fibre length and fibre loading (that is, loading of fiber) were considered as the process parameters. Three levels for each parameter were used. Accordingly, a suitable orthogonal array L9 (33 ) was selected and experiments were conducted. After conducting the experiments the mechanical properties (hardness, and tear strength) of the prepared areca nut fibre - natural rubber composites were measured and (S/N) ratios were calculated. With the help of graphs, optimum parameter values were obtained and the confirmation experiments were carried out, and satisfactory agreement was obtained.
