Soft body armour systems used in military and police forces to protect against handgun and fragments are made from aramid and UHMWPE fibres and textiles. Ergonomy and comfort are of great importance for these systems especially with the adoption of new body armour standards. This recent trend has led to the development of more flexible ballistic materials, based on the use of low denier micro-filament fibres, which minimize restriction to body movements and improve user comfort. This paper presents a new test method developed to measure the stiffness of soft armour systems. An overview of other current methods available and their limitations is also presented. The results indicate that most of the existing methods have limitations regarding the number of plies, and that boundary conditions are very important. In order to validate the new method, experimental tests were performed on different multiple ply materials, such as woven fabrics, felt, unidirectional fibre systems, and hybrid configurations. The effectiveness of the new test method is discussed and recommendations are made on possible improvements.
