Hybrid ballistic solutions
Abstract
ABSTRACT UAVs (Unmanned Aerial Vehicles) are increasingly used in defence and military operations. In these applications platform survivability becomes critical, thereby creating a need to provide the best possible ballistic protection within a restricted mass budget. This fundamental design contradiction pitches higher autonomy (longer missions, increased range) against survivability, risk and total asset availability. In the current article, the authors discuss the development of a lightweight ballistic armour to be implemented in a UAV and assess its behaviour during and after a 7.62 mm bullet impact, showing that the proposed hybrid panels can withstand high-energy ballistic impacts. This paper describes the definition of the various lightweight composite-ceramic armours and selection of the materials that integrate the solutions to be tested, according to the insights in the literature. The paper shows how the different material combinations were validated through the FEM (Finite Elements Method) analysis and why some, more promising solutions, were selected for manufacturing.Experimentally the paper discusses the composite laminates that were obtained through composite prepreg hand-layup (with compaction and cure in autoclave or in press) and VARTM (Vacuum Assisted Resin Transfer Moulding) or infusion processes (Ulven, Vaidya and Hosur, 2003), and the ceramic plates that were manufactured through the sintering technique. Furthermore the work shows how the integration between the two of components was accomplished: by means of a previously characterized adhesive for aeronautic applications; or through the co-curing of composite-ceramic hybrid panel. Finally, the paper shows how the experimental test campaign was run in order to critically observe panel effectiveness after a 7.62 mm projectile impact in the conditions described by NATO STANAG 2920 (3rd Ed.) (The NATO Standardization Agency, 2014) and NIJ 0101.06 standard (U.S. Department of Justice, 2008) in the case of a laboratory test (Luz et al., 2015). Results from the projectile speed monitoring system and high speed camera are used to correlate the collected experimental data, the impact phenomena interpretation from non-destructive damage pattern analysis and FEM simulation models.
