摘要

This present work mainly focused to utilize the natural resources such as Banyan short fiber, wheat gluten (WG) for making the series of different bio degradable polymer composites. The WG was blended with the polyhydroxybutyrate (PHB) bio polymer in the ratios 20:80, 30:70, 40:60 percentage of WG and PHB polymer respectively. A total of nine different ecofriendly nano filler bio composites with the size 300 * 300 * 3 mm were developed through hand layup method with the aid of hydraulic press by changing the dispersed phase (short banyan fiber) composition like 10, 20, and 30 percentage with continuous phase of 90, 80 and 70 percentage (bio polymer blends). The fabricated bio composite laminates were initially tested according to ASTM standard for density, tensile, impact, thermogravimetric analysis, and surface texture analysis. Then the drilling was carried out on the three different composites (30 % banyan fiber reinforced composites) for exploring the surface defects such as surface roughness and delamination. The result inferred that the 30 % banyan fiber composite obtained higher properties at all WG proportions. The optimized result obtained for the 30 % banyan fiber bio polymer blended composite through Taguchi’s L9 orthogonal experiment found to be more impact by the diameter of drill and feed rate applied during machining for resisting the delamination whereas biopolymer blending ratio and feed rate for surface roughness.
