Abstract Scope |
High-performance polymers, such as the polyaryletherketone (PAEK) family, have the potential to replace metals in several applications. A study of the tensile properties of two members of the PAEK family is conducted using two different additive manufacturing (AM) methods. Polyetherketoneketone, both neat (PEKK) and reinforced with 10 wt.% milled carbon fibers (CFPEKK), was manufactured with fused filament fabrication (FFF), and polyetherketone, both neat (PEK) and reinforced 10 wt.% milled carbon fibers (CFPEK), was manufactured with selective laser sintering (SLS). The degree of crystallinity of specimens at various stages was measured by differential scanning calorimetry (DSC) to learn how printing and annealing affect their crystallinity. Tensile fracture surfaces were examined using laser confocal microscopy to determine the fracture mechanisms. Results of this study provide a new understanding of the performance of AM PAEK parts. |
