Abstract

Journal of Thermoplastic Composite Materials, Ahead of Print.
Multiscale simulation of Fused Deposition Modeling (FDM) of Continuous Carbon Fiber reinforced Polylactic Acid (CCF/PLA) is constrained by filament-level geometric complexity. A “100-to-1” downscaling strategy is developed in which a regular filament ...
