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

Abstract

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

Effect of Packaging Materials and Moisture Level on Pearl Millet Stored Under Ambient Condition

“…These results are conformity of those reported by the author [41][42][43]. The author reported that when seed could be packaged in moisture proof containers, the relative humidity of the air around the seed remains low, then the seed equilibrium moisture remains low and the seed maintains its viability and vigour for a longer time [44][45][46].…”

Experimental Investigation of High Filler Loading of SiO2 on the Mechanical and Dynamic Mechanical Analysis of Natural PALF fibre-Based Hybrid Composite

“…Both mechanical and electrical testing was performed on the aramid ber insulation sheet before and following modi cations. A signi cant interfacial impact between nano-SiO 2 and synthetic bers was discovered, resulting in a 1% improvement in tensile strength, deformation at breaking, and dielectric breakdown power [21]. As contrasted to untreated aramid insulation sheets, SiO 2 -modi ed aramid ber insulation paper improved by 7.5%, 10%, and 14%, respectively.…”

Synthesis and Adsorbent Performance of Modified Biochar with Ag/MgO Nanocomposites for Heat Storage Application

“…It might be possible to modify biochar’s characteristics to remove particular impurities to make it more efficient. Biochar has also been thoroughly explored as a cost-effective adsorbent for removing biological and metal pollutants from aqueous and gaseous atmospheric pollutants in environmental protection [32]. Although fresh biochar has a small adsorption capacity, different feed types and process conditions affect its physical and chemical properties (active adsorption sites, size distribution, and charge density) [33].…”
