Methods and results of tests on several models of cylinder-shape fbrous covers, subjected to explosion impact, have been presented. The tested covers consisted of layers of ballistic textile made of para-aramide fbres featuring special structure and between the layers a chamber with various shock absorption layers was created. Moreover, methods of tests of cylinder-shape covers’ resistance to explosion of charges with fragments were presented, considering various parameters of base under the cylinder, sort, location and ways of charge ignition, manners of registering the area of threat and covers’ reaction to the explosions. Having the methods applied, it was shown how the shock absorption layers minimize the effect of decrease of strength of ballistic textile layers of cylinder under the impact of air shock wave, explosion products and metal fragments formed after explosion of charges. In the tests the 200 g TNT bars stuffed with various sorts and numbers of small metal elements, including standard fragments and balls of various diameters, were used. The analysis of both protective capabilities of the covers and the devastation resulting from impact of blast-propelled fragments was performed.
