Experimental Investigation of Drilling Characteristics of Novel Glass Fiber Composite Reinforced with Aluminium Wire Mesh

Abstract

Aim: This study aims to fabricate and evaluate the drilling characteristics and cylindricity tolerance of novel composites reinforced with aluminium wire mesh and plain glass fiber composite material. Materials and Methods: This study works on the fabrication of novel composite materials, these composite materials were prepared using glass fiber and kevlar fiber reinforced with aluminium mesh. The composite material reinforced with wire mesh was taken as an experimental group with a sample size of 20 (N=20). The plain glass fiber composite material is taken as a control group with a sample size of 20 (N=20). The composite sample size was calculated by keeping 80% of G-power. Hand Layup Technique is used for fabricating both groups of composite materials. SPSS software is used for statistical analysis. Result: The mean values obtained by the control group and experimental group were 80.31% and 70.65% respectively. Glass fiber composite reinforced with wire mesh shows better drilling characteristics and also a decrease in cylindricity tolerance, the significant value obtained is p=0.025 (P<0.05). There is a significant difference between the groups. Conclusion: Within the limits of the study, glass fiber composite reinforced with aluminium wire mesh shows a 18% decrease in cylindricity tolerance during dilling. So the reinforced composites can be used in many automobile and marine applications.
