Multiresponse Optimization of Mechanical Behaviour of Calotropis gigantea/Nano-Silicon-Based Hybrid Nanocomposites under Cryogenic Environment

The utilization of natural fibre-based biodegradable polymers has expanded in the present circumstances since fibres are relatively inexpensive, recyclable, lighter, nonflammable, and harmless. However, hydrophilic nature is most serious issue. To address this issue, current study was applied to enhance material characteristics hybrid composites strengthened by CGF nanosilica powder. accomplish mentioned goal, RSM calculated optimized following processing parameters using BBD arrangement at various fibre thickness (gsm), weight percent powder (wt. percent), cryogenic treatment period (min). prevent nature, were pretreated for four hours with a 5% alkaline solution. Deterioration models created analyze characteristics, optimal progression variables determined. Based on multiresponse surface methodology, governable process nano-silica- CGF-based nanocomposites should be set 3% silica, 300 gsm CGF, 30 minutes treatment. tension, bending, impact property correlation coefficient values ( R 2 ) 0.95, 0.94, respectively. above-mentioned combinations provide better water absorption mechanical strength.
