Our first step was to understand the make up of the current solution and see whether we could offer any improvement. The customer had evolved the solution over a number of years and without increasing material costs significantly this option was not possible.

We then analysed the spall coming off the back of the current solution and with the ballistics range, we calculated an approximate velocity for the spall. Using this velocity and working out the dimensions and hardness of the spall coming off, we then worked with our lightweight materials and offered two possible solutions.

The customer then tested again, and we had success with both solutions, but our flexible Aramid PA material was chosen to be cost effective and has now been added to the design. Added to the work carried out on choosing the material, we also worked on the design to fix the flexible panel in place without any need for drilling holes or excessive and costly profiling.
