Hemp/glass woven fabric reinforced laminated nanocomposites via in-situ synthesized silver nanoparticles from Tilia cordata leaf extract

The reinforcement of natural and artificial fiber-oriented woven fabrics with thermosetting polymers is getting popularity nowadays. The hybridization of natural hemp with glass could facilitate the developed composite panels to be a potential candidate for automotive parts. Both hemp and glass-woven fabrics were treated with greenly synthesized silver nanoparticle (AgNPs) obtained from Tilia cordata leaf extracts and then composited by using thermosetting epoxy resin. Three composite panels were developed from five consecutive layers of glass- and hemp-woven fabrics (sequence is glass, hemp, glass, hemp, glass); in two of them the fabrics were loaded with 1% and 5% AgNPs, respectively, the third one was prepared without any nanosilver loading. The presence of green AgNP was tested and confirmed by using XRF (X-ray fluorescence) and ICP OES (inductively coupled plasma optical emission spectroscopy) test. The developed hybrid composites were characterized for thermal, mechanical, physical, and morphological performance and found satisfactory results. Statistical analysis of the test results also confirmed the positive influence of nanosilver loading on hybrid composites. However, the developed biocomposite panels could facilitate the industrial production units with most advanced, feasible, and multi-functional laminated products.

Automated summary

The reinforcement of natural and artificial fiber-oriented woven fabrics with thermosetting polymers, in combination with the hybridization of natural hemp and glass composites using greenly synthesized silver nanoparticles, resulted in satisfactory thermal, mechanical, physical, and morphological performance. The positive influence of nanosilver loading on hybrid composites was confirmed through statistical analysis, suggesting potential for advanced and multi-functional laminated products in industrial production units.
