Physical protection: Interdependence between hard armour and soft armour – RMIT University
Dr Rajneesh Jaitlee from RMIT University completed his PhD dissertation in 2014. The aim of Dr Jaitlee’s research work was to study the interdependence between hard armour and soft armour systems. The study investigated the effects of cladding on ceramics and improving their fabrication methodology. During the research work, different composite armour styles were fabricated using commercial grade aramids. The research focus was complemented by a series of mechanical tests followed by a series of ballistic tests against a range of military grade projectiles across different velocity ranges. The research concluded that by improving the fabrication techniques used for cladding the ceramic tiles using high performance commercial grade aramid, the back face signature can be reduced and can thus have the potential to mitigate soldier injury.
Dr Jaitlee’s work contributed to DMTC Project 3.3 – Advanced Personnel Armour. The project emphasised the design and development of armour styles using new advanced material systems for physical protection comprising advanced textile substrates- such as commercial grade aramids, ceramics, polymer composites and commercial-grade epoxy resins. As threats to Australian Defence Force personnel continue to evolve, there is an urgent requirement for higher performance armour materials to increase the level of protection offered, with a simultaneous requirement for reducing weight and bulk for increased mobility. Dr Jaitlee’s project contributed directly to the project aims by building a body of knowledge in the area of hard and soft armours. The project adopted a collaborative approach among defence industry and research organisations Australian Defence Apparel (ADA), Defence Science and Technology Organisation (DSTO) and RMIT University. The project contributed to enhancing new fabrication methodologies that may be used to minimise Back Face Signature. Dr Jaitlee is keen to establish his career where he can utilise his skillset in the area of ballistics and armour applications and dedicate the experience gained during his research work.
