Mechanical Properties of a PLA/Nettle Agro-Composite with 10% Oriented Fibers

Within the framework of environmental policies which tend toward new ecological materials, without use petroleum-based objective this work is to develop a composite 100% natural associating fibers European nettles (Urtica Dioica) and PLA (Poly-Lactic Acid). After having determined properties both components composite, methodology was implemented maximize PLA/nettle association. Then, tensile tests with standardized specimens were carried out assess mechanical characteristics are ultimately very dependent on its manufacturing process. Experimental results demonstrated that process in material enhanced overall properties, compared those found literature (Young’s modulus: 5.41 ± 0.23 GPa vs. 1.2 4.37 0.14 GPa). Our findings suggest widespread although clearly stem from quality nettle fiber, itself highly variable parameters linked growing conditions plant. The possible applications eco-friendly seem be wide, as long they do not have undergo too important structural loads, for example sector interior furniture, packaging, or even elements automotive sector.
