Testing method for ceramic armor and bare ceramic tiles
conference paper
TNO has developed an alternative, more configuration independent ceramic test method than the standard Depth-of-Penetration test method. In this test ceramic tiles and ceramic based armor are evaluated as target without a semi-infinite backing layer. An energy approach is chosen to evaluate and rank the target materials penetration resistance. By measuring the armor material’s energy absorption, subtracting the residual projectile energy after penetration from the projectile energy before impact, an objective performance parameter for the ceramic or ceramic based armor is obtained. However, this parameter is still related to the specific projectile used in the test. The presented alternative testing method for ceramic based armor 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, capturing the penetrated projectile (and ceramic fragments) in a water basin. Analysis of the projectile remains after the impact event, provides valuable information on the two projectile to target interaction stages, dwell and penetration. The test method and analysis method are described in this paper. Results on ceramic and ceramic based armor are presented and discussed.
