Measurement of surface roughness of epoxy matrix nanocomposites reinforced with bi-directional sisal fiber with novel graphene nanoparticles fabricated by hand layup method.

This work aims to measure the drilling operation and surface roughness of sisal fibre without filler (epoxy) matrix nanocomposites reinforced with innovative bi-directional sisal fibre with graphene laminated by hand layup. Materials and Methods: In surface roughness, sisal fibre reinforces. By making plates, resin and hardener form a matrix and graphene fills it. Sisal fibre without filler (N=20) and graphene (N=20) are tested in the control group. Results and Discussions: Sisal without filler (0 percent) and sisal with graphene (4 percent) have good surface roughness. SPSS programme indicates significance (p<0.05) and ANOVA analysis indicates 0.001. Conclusion: Sisal with graphene (4%) exhibits more surface roughness than epoxy matrix sisal without filler, within the study's limits (0 percent). The surface roughness of epoxy composites with 4% graphene (filler) was 15% higher than simple epoxy composites. [ABSTRACT FROM AUTHOR]
