The Big Area Additive Manufacturing (BAAM) system can print structures on the order of several meters at high extrusion rates, thereby having potential to significantly impact automotive, aerospace and energy sectors. functional use such parts, however, may be limited by mechanical anisotropy, in which strength printed parts across successive layers build direction (z-direction) lower than corresponding in-plane (x-y directions). This has been primarily attributed poor bonding between since...
Carbon fiber (CF)-reinforced thermoplastic composites have been widely used in different structural applications due to their superior thermal and mechanical properties. The big area additive manufacturing (BAAM) system, developed at Oak Ridge National Laboratory’s Manufacturing Demonstration Facility, has manufacture several composite components, demonstration vehicles, molds, dies. These components designed fabricated using various CF-reinforced thermoplastics. In this study, the dynamic...
Abstract To develop new materials for extrusion additive manufacturing (AM) systems, a fundamental understanding of rheological properties is essential to correlate the effect processing on material structure and its properties. In this work, five different grades neat carbon fiber (CF)‐reinforced poly(ether ketone ketone) are reported. Rheological understand reinforcing fibers AM process parameters such as time, temperature, environment, shear rate flow behavior during processing....
Abstract With the advent of additive manufacturing, lattice structures have been increasing interest for engineering applications involving light‐weighting and energy absorption. Several studies investigated mechanical properties various lattices made up mostly unreinforced polymers lack numerical analysis reinforced structures. In this paper, response short fiber under compression is through experiments simulations. Three different 2D namely, square grid, honeycomb, isogrid along with their...
