Abstract
This work’s main objective is to assess MRR (Material removal rate) of novel hybrid epoxy composites reinforced with sustainable natural fiber (5%) and nano sized carbon particles (5%) in comparison to plain epoxy during CNC drilling. The samples for both groups were made by a simple layup method. The work samples were prepared in accordance with the specifications, and drilling was carried out using a vertical CNC machine for a total of 20 experiments, in order to evaluate and compare the MRR of the samples, with a pretest G-power of 80%. T-independent tests were conducted using the SPSS (Statistical Package for the Social Sciences) statistical software to evaluate the material clearance rate. The average material removal rate for group 1 pineapple fiber mat nano carbon particles (5%) was 0.3739 mm3 /sec, compared to 0.1283 mm3 /sec for group 2 (Plain epoxy). Based on the findings of the t-test statistical analysis, it is concluded that the mean variance of MRR between groups 1 and 2 under study is statistically different (Significant of p = 0.002, which is p < 0.05). It is clear, within the constraints of this investigation, that adding reinforcements like pineapple fiber and nano carbon particles has a significant effect on raising MRR.
