Abstract

Recycling of materials effects the environment and thus greater impetus is being given to develop materials like biodegradable composites from renewable sources. A biodegradable composite is made up of natural reinforcements and matrices that are environment friendly. Natural reinforcements in matrices that are biodegradable have several advantages like reasonably good specific modulus, low cost and abundant availability in comparison to synthetic reinforcements. In this study areca frond fibres are reinforced with calcium carbonate and rubber latex as binders, starch, and water, vinegar as base material and glycerol as plasticizer. Matrix ingredients included corn starch (15-30 g), water (30-60 g), vinegar (5-10 g), calcium carbonate (5-10 g), rubber latex (5-10 g) and glycerol (10-20 g). A fusion of hand layup and compression moulding technique was used to prepare composite panels. Taguchi method is an optimization technique to reduce number of desired experiments while maintaining quality of data collected and for finding the significance of various factors and their levels which affect the response. Taguchi method with L8 orthogonal array with six factors and two levels combination was used for experimentation. Specimens for the flexural tests were cut out from the prepared panels and tests were performed in accordance with ASTM standards. Maximum flexural strength of 48.54 MPa was obtained with a combination of corn starch (30 g), water (30 g), vinegar (10 g), calcium carbonate (10 g), rubber latex (5 g) and glycerol (20 g). Analysis of variance (ANOVA) was performed on the obtained data and S/N (signal to noise) ratios for larger the better quality characteristics was calculated. Results indicated that rubber latex has the maximum effect (33.18%) on flexural strength of the biodegradable composites followed by corn starch, vinegar, calcium carbonate, glycerol and water.
