This study presents mechanical characterization of short fiber-reinforced 3D printed components. It was found that short carbon fiber-reinforced PET exhibits higher elastic modulus, tensile, and shear strengths compared to ABS.
Short fiber-reinforced 3D printed components are high performance materials with a wide range of potential applications in various industries ranging from aerospace to automotive. Mechanical characterization of 3D printed short carbon fiber polyethylene terephthalate and acrylonitrile butadiene styrene parts are presented under the application of shear load in this study. The anisotropy properties of both composite and polymer materials were investigated by printing samples at two different orientations, using fused deposition modeling (FDM) technique. The fabricated samples were subjected to tensile and shearing loads while 2D digital image correlation (DIC) was used to measure full-field strain on the specimen. The obtained results revealed a noticeable anisotropy in shear properties as the function of printing orientation. Moreover, it found that using carbon fiber-reinforced PET results in higher elastic modulus, tensile, and shear strengths up to 180%, 230%, and 40% compared to ABS.
