Abstract :

Driven By The Need For Lightweight, High-strength Materials In The Automotive Industry To Improve Fuel Efficiency And Reduce Emissions, Composite Materials Have Gained Significant Importance. The Present Study Focuses On The Fabrication And Characterization Of Multi-Walled Carbon Nanotubes (MWCNTs) Reinforced A357 Aluminium Alloy Metal Matrix Composites For Lightweight Automotive Applications. Composites Were Produced Using A Hybrid Processing Route Combining Mechanical Alloying Through Ball Milling And Vacuum-assisted Stir Casting To Ensure Uniform Dispersion And Improved Bonding. The Reinforcement Content Was Varied From 0 To 2 Wt.% In Increments Of 0.5 Wt.%. Mechanical Testing Revealed A Significant Improvement In Tensile Properties With The Addition Of MWCNTs. The Composite Containing 1.5 Wt.% MWCNTs Exhibited The Highest Tensile Strength Of 172.4 MPa, Indicating Optimal Reinforcement Content. Beyond This Level, Agglomeration Effects Slightly Reduced Performance. However, Optical Micrograph Of The High Tensile Strength Sample Depicts Better Grain Refinement Of 72 µm Compared To 174 µm Of Pure Sample. On Overall, The Results Demonstrate That Controlled Addition Of MWCNTs Effectively Enhances Strength And Makes The Composite Suitable For Structural Automotive Components
