Abstract | The performance of a new class of metal fiber reinforced polymer (FRP) produced by additive manufacturing (AM) is discussed and compared with a commercially availablepolyethylene terephthalate glycol-PETG/carbon fiber composite. Aluminum alloy micro-fibers (Al6061-T6) produced by Modulation-Assisted Machining (MAM) are dispersed in a thermoplastic PETG matrix by screw extrusion. The filaments are feedstock for AM processing and sample preparation by fused deposition modeling (FDM). Mechanical testing, micro-hardness and wear testingprotocols were used to evaluate the performance of the new FRP.ThePETG/AlFRP composite samples show performance advantages over samples printed from commercially available PETG/carbon fiber filament.Computerized tomography (CT) and scanning electron microscopy (SEM) are used to explore the characteristics and distribution of the aluminum micro-fiber in the composite and the fracture surfaces in the test samples. AM processing with these new metal fiber/matrix formats enabled by MAM has unique potential to access high-performance composites applications. |
