Flexural Performance and Morphological Characterization of Graphene Nanoparticle‐Reinforced Polylactic Acid (PLA) Nanocomposites

Journal of Polymer Science, EarlyView.
PLA/GNP filaments containing 0–1.6 wt% graphene are produced by melt compounding and fabricated into flexural specimens using FDM. Their mechanical response and fracture morphology are evaluated through ASTM D790 three‐point bending tests and SEM. Increasing graphene loading promotes agglomeration and interlayer defects, reducing strength, stiffness ...
