FE modeling of continuous fiber reinforced thermoplastic composite structures produced by additive manufacturing

Abstract

Abstract Additive manufacturing is process of joining material, bringing many benefits such as customization and low production cost. Markforged developed Continuous fiber fabrication technology, which allows to print continuous fiber reinforced thermoplastic (CFRTP) composites. Although printed CFRTP parts achieve mechanical properties better than another 3D printed counterparts, there is demand to gain suitable mechanical properties comparable with conventionally manufactured parts using improvements in printing parameters and fiber deposition. In this paper, the main goal is analyzing of geometry constraints of fiber deposition and modeling options in FEM program ADINA. Additionally, stress distribution analysis with regard to stresses in matrix and fibers will be performed.
