Abstract (EN): The evolution of materials used for anterior cruciate ligament (ACL) ruptures repair has been remarkable, currently emerging from cooperation between Mechanical Engineering, Biomaterials and Tissue Engineering. Currently, regarding this application, biodegradable polymers like polylactic acid (PLA) have been researched as a solution, however its mechanical characteristics must be improved with reinforcements, namely its mechanical resistance to fatigue, preventing laxity or rupture of the device. Concerning to PLA viscoelastic behaviour influence on these device issues, it is presented a experimental creep mechanical study of some PLA-matrix nanocomposites reinforced with carbon nanoparticles, particularly carboxyl functionalized carbon nanotubes (PLA/MWCNT-COOH), showing permanent strain reduction accumulated on nanocomposites.
