講座題目：
Additive manufacturing of continuous fiber composites using fused filament fabrication
講座內容：
Fused filament fabrication (FFF) has been extensively studied in recent years because of its capability for manufacturing continuous fiber composite parts. The successful fabrication of high quality continuous fiber composite parts using FFF is secured by completion of a few key mechanisms such as precise deposition of a filament and fusion between a depositing filament and filaments deposited in previous steps, while the fusion is modulated by two key mechanisms, i.e., “intimate contact” and “autohesion”. This presentation summarizes some recent results on additive manufacturing of comtinuous CF/PA composites. A mechanistic model is developed to describe “intimate contact” and “autohesion” processes during the “interlaminar” deposition mode, equipped with parameters such as surface profile of depositing filament, temperature of depositing head, contact duration between filaments, contact pressure between filaments, while the latter is measured by a high precision 3D dynamometer instrumented on the 3D printing platform. It is concluded that a high quality pre-impregnated filament of a precise diameter and high precision deposition of the filament in a defined path with a tailored processing window of deposition temperature, depositing speed, and deposition pressure are the keys for the successful fabrication of high quality continuous fiber composite parts using FFF.
