The aim of this study is to ultimately improve the multi-hit capability of armoured constructs. To gain an understanding of how different armoured layers respond to impact, and distribute the stress within the armour pack. In this study an investigation into possible adhesives and surface treatments for armoured constructs is conducted, first at a laboratory level, followed by full scale ballistic testing. A joint will always fail at its weakest link, so understanding and manipulating these interfaces will ultimately improve the multi-hit capability of vehicular armour. Furthermore an investigation into whether an interphase is formed with the adjoining substrates has been carried out. The adhesives and interphase layers help determine the distribution of stresses within an armour pack. A two part epoxy with and without nano-fillers, an elastic two-part adhesive and a silicone were used in this study. The interphase study was completed using Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC).
