3D processing and characterization of acrylonitrile butadiene styrene (ABS) energetic thin films

Progress in Additive Manufacturing of Energetic Materials: Creating the Reactive Microstructures with High Potential of Applications

“…lished a series of papers on the manufacturing of thermitebased films using this approach [42][43][44][45]. The influence of the polymer and solvent type on the structure and performance of Mg/MnO 2 deposits was established [43].…”

“…The authors reported an intimate relationship among the initial mixture properties, the thickness and density of the produced film, and the flame speed [42]. More complex compositions have been produced by blade casting, i. e., Al/ MoO 3 /KClO 4 in silicone polymer (Mold Max™ 30)/xylene [44] and acrylonitrile butadiene styrene plastic (ABS)/acetone [45]. The still images from the video of the combustion of compositions where the ABS content exceeds 40 wt.% reveal the noticeable flame standoff distance, which is a consequence of the slow oxidation rate of polymer destruction products.…”

Rheological Considerations for Binder Development in Direct Ink Writing of Energetic Materials

“…For example, mock energetic formulations containing pentaerythriol particles and polydimethyl siloxane (PDMS) binder at 80 vol% particle loadings [21], acrylonitrile butadiene (ABS) with acetone solvent and energetic materials at 50 vol% particle loadings [22], and three different Semtex formulations, typical PBX [23], have all been examined. The studies demonstrated that the formulations had a high viscosity and were shear thinning with a yield stress as seen by a higher increase in viscosity at low shear rates [21][22][23]. They were highly elastic fluids, with a storage modulus that was much larger than the loss modulus [22,23].…”

They were highly elastic fluids, with a storage modulus that was much larger than the loss modulus [22,23]. These results indicate that the PBX behaves similarly to other HLS, but the studies do not thoroughly investigate the effects of binder properties, such as molecular weight and binder viscosity, on the rheology of the slurry.…”

Pyrotechnic Films Based on Thermites Covered with PVC

“…Pyrotechnics are usually prepared as pyrotechnic powder mixtures from which they may also be pressed or extruded into pellets [1][2]. The pyrotechnic mixtures may also be combined with binders and solvents to become slurries and pastes for traditional pyrotechnic ignition purposes [2], or deposited as thin films to advance 3D printing of pyrotechnics [3]. The manufacture of thin pyrotechnic films can also be made through electrophoretic deposition [4], and by magnetron sputtering where the pyrotechnic fuels and oxidants are vacuum deposited as thin layers [5].…”
