Abstract

TNO developed an alternative, more configuration independent ceramic test method than the Depth-of-Penetration test method. In this alternative test ceramic tiles and ceramic based armour are evaluated as target without a semi-infinite backing layer. An energy approach is chosen to evaluate and rank the target materials penetration resistance. The alternative testing method for ceramic based armour uses a high speed camera technique to determine residual velocity of target material fragments and of projectile remains. The residual mass of the projectile is determined after capturing the residual projectile in a water basin. Analysis of the projectile core fragments after the impact event, provides valuable information on the status of the core and mass of its fragments. Subtracting the residual kinetic energy from the initial energy of the core of an AP round, the energy absorption of the projectile-target interaction process is obtained with a limited shot-to-shot variation. This provides an accurate and objective performance parameter for the ceramic or ceramic based armour. The test method and analysis procedure are described in this paper. Results on ceramic and ceramic based armour are presented and discussed.
