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