This study compares PLA reinforced with natural fibers (hemp, flax) tomodified PLAs: PLA Plus (additive-enhanced) and PLA CF (synthetic carbon-fiberreinforced). Mechanical behavior is assessed via tensile, compression, and impacttests, complemented by microscopy-based microstructural analysis to evaluate per-formance differences in detail experimentally. The findings of the study indicatethat, in impact and compression tests, PLA Plus offers the best performance, show-ing a 15.278 KJ/m2 in the average energy per surface for the impact test and, anelastic modulus of 1.69 GPa and yield stress of 85.7MPa, while PLA hemp exhibitedvalues that were either equal to or highly comparable to those obtained by PLA CF.In the tensile tests, the PLA CF shows the best results, the modulus value obtainedwas 6.69 GPa, exhibiting a modulus value that was 146.30% higher than that of thePLA hemp and 167.37% higher than that of the PLA flax. Finally, a thoroughexamination of the scanning electron microscopy (SEM) images revealed that theobserved properties could be attributed to a reduced number of bubbles anda higher proportion of reinforcement fibers when compared to the natural fibers(NF) filaments examined. 000168600 536__ $$9info:eu-repo/grantAgreement/EC/H2020/101079009/EU/SUSTainable industrial DESIGN of TEXtile structures for composites/SustDesignTex$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 101079009-SustDesignTex 000168600 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc$$uhttps://creativecommons.org/licenses/by-nc/4.0/deed.es 000168600 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000168600 700__ $$aLemmi, Tsegaye 000168600 700__ $$0(orcid)0000-0002-9702-9314$$aMiralbes, Ramon$$uUniversidad de Zaragoza 000168600 700__ $$0(orcid)0000-0001-8451-660X$$aRanz, David$$uUniversidad de Zaragoza 000168600 7102_ $$15002$$2305$$aUniversidad de Zaragoza$$bDpto.
