【 摘 要 】

Ballistic protection is a matter of interest requested by civilian as well as military needs. The last decade has witnessedan increase in the use of light weight and efficient armour systems. These panels may be used for body protection aswell as light vehicle protection against small calibres or to enhance the protection level of heavier vehicles with decreasingor maintaining their weight penalty. Ultra high molecular weight polyethylene is a material of interest for light weight armourapplications. The authors designed panels made of hot–pressed Tensylon® in different configurations with thin steel sheetsas a backing and shield protection. Comparison of their ballistic performance to the theory predictions reveals the improvedballistic response of the panels. In addition, a non–pressed Tensylon® panel has been tested in order to facilitate the observationsof the failure mechanisms inside the panels. Even if not suitable for practical use, such non–pressed panels clearlyreveal the dynamic processes at micro–scale that occur during the impact. The failure mechanisms of the material underbullet penetration are discussed based on photography, optical microscopy and scanning electron microscopy. The supposedeffects of the panel pressing are discussed based on the observed difference between pressed and non–pressed structuresballistic response.
