EVALUATION OF THE TENSILE AND MORPHOLOGICAL PROPERTIES OF PLA/CNF NANOCOMPOSITES OBTAINED BY 3D PRINTING

EVALUATION OF THE TENSILE AND MORPHOLOGICAL PROPERTIES OF PLA/CNF NANOCOMPOSITES OBTAINED BY 3D PRINTING

"The use of cellulose nanofibril as a reinforcement into the poly(lactic acid) - PLA matrix, can improve the mechanical resistance and elastic modulus of PLA and thus enable the use of this polymer in varied applications. This work aimed to develop and characterize PLA nanocomposites with 0.5; 1 and 2% of cellulose nanofibril prepared by extrusion, followed by 3D printing. The samples were evaluated by tensile testing and optical microscopy. The results showed that there was variation in the surface morphology of the specimens in the same formulation, however the tension at maximum force, modulus of elasticity and deformation at rupture showed that there was no statistical difference between pure PLA and composites. This result was probably due to by non-cellulosic materials (waxy) present in the nanoparticles."
