Influence of Copper foil Reinforcement on the Mechanical and Drilling Efficiency of Sisal/Flax epoxy Composite 2020-28-0416
In this developing world the need of light weight and high strength materials are increasing in various industries. As a result of above the importance of natural fibre is also increasing to satisfy the industrial need. In manufacturing industries for the assembly of engineering components the drilling is one of the important operations. The main objective of this research is to determine the mechanical properties and drilling efficiency of natural fibre composite. Sisal/flax as a natural fibre, the copper foil of thickness 0.025mm as a structural reinforcement and Epoxy resin as a matrix were used for making composite. The hand layup technique was used for fabrication of composite. Two different sample of composite were fabricated C1 (sisal of thickness 0.7mm, flax of thickness 0.96mm, copper foil was punched with holes (Ø5mm), 20mm apart and 90° to each other) and C2 (sisal of thickness 0.7mm, flax of thickness 0.96mm, copper foil punched with holes (Ø5mm) 20mm apart and 45° to each other). After fabrication of composite the test sample were cut and tested according to ASTM standard. The mechanical properties such as flexural, tensile and impact were determined. The lamination and quality of composite plays a vital role in the calculation of drilling efficiency. The CNC milling machine was used to test the drilling efficiency of the fabricated composite. The CNC milling machine is connected to dynamometer to measure the thrust force during drilling operation. In this research, it was found that the impact strength of C1 (1.25J) was better than C2 (1.15J), flexural strength of C2 (49.99MPa) was better than C1 (26.57MPa) and tensile strength of C2(16.9 MPa) was better than C1(14.75MPa) specimen.
