Drilling Process Parameter Optimization And Mechanical Property Test Analysis Of E-Glass-Sisal Fiber Reinforced Polyester Composite

Abstract

When Focusing On Composite Materials, The Most Important Factors To Consider Are Environmental Friendliness And Lightweight With High Specific Qualities. The Growing Use Of Composite Materials In A Wide Range Of Applications Raises The Need For High-Quality Drilling Of These Materials. The Effect Of Stacking Sequence And Drilling Parameters On E-Glass-Sisal Fiber Reinforced Polyester Was Investigated In This Paper. Hand Layup Was Used To Create Hybrid Fiber/Polyester Composites With A 40:60 Ratio. A 3d Optical Profilometer Was Used To Determine The Surface Roughness Values. Delamination And Circularity Errors Were Analyzed Using Imagej Software. Mechanical Properties Using Impact, Hardness, Flexural, And Tensile Testing And Drilling Behavior Using High-Speed Steel Cutting Tools In A Cnc Machine Were Determined. Using Taguchi L16 Orthogonal Array And Grey Relational Analysis Methods To Find Optimized Parameters (Speed, Feed Rate, Stacking Sequences, And Drilling Diameter As Process Control Variables With Multiple Performance Characteristics Of Delamination Factors, Circularity(Roundness) Error, And Surface Roughness Are Determined. Chip Formation And Hole Morphology Were Also Assessed. From The Result, An Impact Energy Of 12.33j, A Hardness Value Of157.633hv, A Flexural Strength Of 387.557mpa, And A Tensile Value Of 132.7mpa Were Obtained. Analysis Of Variance Has Been Used To Find The Effect Percentage Contribution And Significance Of The Process Parameters. Speed, Feed Rate, Drilling Diameter, And Stacking Sequences Were Found To Be The Significant Factors Affecting The Entry And Exit Delamination Factors, Circularity, And Surface Roughness Output. Lower Entry And Exit Delamination, Lower Circularity Error, And Lower Surface Roughness Were Obtained At Speed Of 1500rpm, Feed Rate 0.02mm/Rev, Drill Bit Diameter 6mm, And Sisal/Glass/Glass/Sisal Reinforced Polyester Composite. Conclusions Contribute To The Understanding Combination Of The Taguchi And Grey Relational Analysis To Find The Optimum Process Parameter Which Minimizes The Delamination Factor, Circularity Error, And Surface Roughness Within The Range Of Parameters Investigated
