In this paper, a relatively new and mathematically potent tool of MCDM (Multi-Criteria Decision Making) in the form EDAS (Evaluation based on Distance from Average Solution) approach has been proposed for ranking thirteen candidate cotton fabrics basis four fabric parameters/attributes namely cover, thickness, areal density, porosity. The selection have done with view to achieving optimal thermal comfort properties. Sample no. 3 highest appraisal score 0.9838 achieves rank 1 (best choice) whereas sample 6 lowest 0.0000 occupies 13 (worst choice). results obtained by method demonstrates significant agreement performance earlier methods, which is evidenced very high correlation coefficients (Rs >0.87). Ranking patterns given imaginary weight sets also possess degree higher than 0.90. Moreover, there no occurrence reversal even when initial decision-making matrix changed. Thus, sensitivity analyses changing criteria weights that through influence dynamic decision matrices further bolster stability robustness terms performance.

The addition of nano-additives provides a path to improve joint performance. However, it is not clear if the use these materials can alter susceptibility bonded joints presence defects. This work aims shed some light on this matter, by testing performance defective with adhesives modified nano-additives. Two different kinds carbon-based nano-platelets, including graphene (G) and oxide (GO), were used in as additives for bond single lap (SLJs). Bulk specimens, well three geometrically SLJs manufactured tested. One configuration was without defects (WO), another disbond defect middle overlap, edge known side (SD). These specimens neat epoxy adhesive same 0.3 wt% G GO. GO found Young’s modulus strength adhesive, while also decreasing its toughness.
