摘要：
Ballistic tests of hot-pressed panels of thickness 2.6-5.4 mm made of Dyneema® (HB2 and HB80), aramid (Twaron® No. 613 and Teksar®), and basalt (TBK-100) woven fabrics were carried out. It is shown that the energy absorption efficiency of the panels based on Dyneema® is by 30-75% higher than the other ones at the same suface density. For the panel based on Dyneema® HB80, which showed the best results in ballistic tests, a low-parametric finite-element model to describe its interaction with a high-speed spherical striker is created. This model allows one to predict both the residual speed of the striker and the size of delamination zone with sufficient accuracy.
