Abstract
AbstractAdditive manufacturing (AM) is a process of fabricating 3D parts layer upon layer until the final product is manufactured. This technology is employed in the engineering applications mainly in aerospace, automobile, medical implants, and textile, etc. In nowadays, most of the composite parts are fabricated using AM technologies due to easy production process, relatively high accuracy of produced parts, less material wastage, huge range for material selection, and economic factors. During the production of composite materials, reinforcement content plays an important role in defining the strength, stiffness, and other properties of the composite structure. In this study, porous continuous carbon fiber reinforced polymer composite (CCFRPC) structures are fabricated using fused deposition modeling (FDM) extrusion based technology. Porous CCFRPC structures are additively manufactured using two types of infill patterns (grid and triangular) printed at three different infill densities levels (20%, 40%, and 60%). After the fabrication process, the content of continuous carbon fiber (CCF) in the composite is calculated and estimated using dissolution method. For the dissolution ASTM D 3171 standard procedure is used in order to define carbon fiber content in porous structures. The results show that triangular infill pattern contains more reinforcement content (CCF) compared to grid infill pattern. Moreover, higher reinforcement content in the structure is observed when infill density of the specimen is increasing.
