Abstract

Aim: The objective of this paper is to investigate the surface roughness of 10% of pista shell powder reinforced epoxy composite
compared to plain epoxy resin composite. Materials and Methods: Experiment was done by forming two groups namely Group 1 (Plain Epoxy Resin composites) and Group 2 (10% of Pista shell powder reinforced epoxy composite). The sample size calculation was done using a G power calculated and pre-test power is 95%. The mean value and standard deviation are 0.5 and 0.1 for without filler and with filler was 0.2 and 0.06 respectively and 16 samples per group were taken for study. Heavy calcium carbonate is contained in the pista shell. SPSS software tool was used for statistical analysis. G power is taken as 80%. Results: It was obtained from the results that the surface roughness of the plain epoxy resin composite was 0.443µm and for 10% of pista shell powder reinforced epoxy composite it was 0.661µm. The significance value which was obtained from the statistical value analysis was P=0.029; p<0.05 and hence there is no significant variation observed between the groups. Conclusion: Within the limitations of the studies, it was found that the surface roughness of novel polymer composite for 10% of pista shell reinforcement epoxy composite was better than the plain epoxy resin composite by approximately 35 percent.
