Optimal Design Based on Fabricated SiC/B4C/Porcelain Filled Aluminium Alloy Matrix Composite Using Hybrid AHP/CRITIC-COPRAS Approach

In this present study, SiC, B4C and waste porcelain reinforced AA7075 alloy composites are fabricated by adopting stir casting approach. Twelve formulations based on different weight percentages of reinforcers (3 wt.%, 4.5 6 wt.% 7.5 wt.%.) were manufactured afterward analysed in terms physical, mechanical, corrosion tribological performances. The less than 53 ?m size consistently blended molten accompanied stirring process. To identify the best suitable formulation density, hardness, tensile strength, compressive flexural friction coefficient, wear rate fixed as selection criteria. composite containing (ASBP-8) exhibited highest mechanical strength (Hardness=162 Hv; Tensile strength= 298 MPa; Compressive 221 Flexural 267 MPa), whereas performance (at 40 N load 1300 m SD= 0.00261 g; at 5.026 m/s SV 0.0231 g) coefficient 0.536 0.47 remain lowest for (ASBP-11) composites. density remains (ASBP-12).Since no single composite(ASBP-1 to ASBP-12) could merely satisfy all desired characteristics; end, study applied a novel hybrid AHP/CRITIC-COPRAS method optimal alternative material automotive components. each evaluated was determined establishing criterion importance applying inter-criteria correlation (CRITIC) analytic hierarchy process (AHP) methods. ranking using complex proportional assessment (COPRAS) method. evaluation indicated that (ASBP-12) possesses solution be used applications.
