Within the previous CACHMAP project, experimental and data processing methods have been developed and demonstrated the principle of cavitation phenomena in confined flows. The present project is a step forward which consists in proposing an assembly for the purpose of ballistic protection much more lighter that currently available materials. The consortium wishes to deal with the case of transparent ballistic protections involving the civilian and military world in multi-impact: personal protections of the combatant, protections for vehicles, protection of infrastructures etc. The various technological bricks from fluids to microstructures would be integrated into a set that makes it possible to perform representative ballistic tests. The objective of the project is to obtain a ballistic plate including the concept of transparent cavitating armor. The targeted applications are:- The transparent protections of the fighter to counter ballistic threats of 9 mm or fragments. These protections are currently in PMMA or Polycarbonate. The introduction of a fluid phase in a transparent assembly would reduce the weight of the protection by 20% given that PMMA is 20% heavier than water. - Protections for vehicles (windows) against 7.62 API BZ threats at level 1 and 2 at first.
