Abstract : This paper discusses the effect of granite filler on the mechanical properties (flexural strength and impact strength), biodegradable characteristics, and damping behavior of silk-sisal composites. The hand layup method is used to fabricate the three layers of plain weave mat with varying weight percentages (2, 4, and 6 wt.%) of granite filler hybrid structure. According to the experimental results, the flexural strength value of the developed silk-sisal hybrid composites increases as the weight percentage of the granite filler content increases. In addition, adding 6 wt.% of granite filler content, which is approximately 75.8% higher damping than that of pure silk-sisal. The biodegradable behavior of silk-sisal hybrid composite has also been analyzed and well discussed in this paper.
