Flexural and tensile tests are conducted on specimens of both materials, following the specifications of ASTM D790 and ASTM D638 standards, respectively, to evaluate parameters such as elastic modulus, maximum force and stress, and deformation. The objective is to compare the behavior of these materials and determine their suitability for different biomedical applications. The tests reveal significant differences between PLA and carbon fiber. In bending, carbon fiber exhibits greater stiffness with an elastic modulus of 2.80884 GPa compared to 2.61646 GPa for PLA. However, PLA demonstrates higher strength, withstanding a maximum force of 99.6698 N and a maximum stress of 69.3779 MPa, exceeding carbon fiber's 77.9493 N and 54.1053 MPa, respectively. In tension, the trend continues: carbon fiber shows higher stiffness of 2.43907 GPa but lower force of 1298.92 N, while PLA has lower stiffness of 2.10003 GPa but resists higher forces of 1793.46 N. The results suggest that PLA is more suitable for applications requiring flexibility and the ability to withstand stresses before rupture, such as temporary devices. Carbon fiber, on the other hand, is ideal for applications demanding high structural stability and fatigue resistance, such as permanent implants where weight must be minimized. |
