The unit has an aramid fabric panel stack formed of a sub-stack of panels (1) and another sub-stack of panels (2). Each panel of latter sub-stack is provided with an associated reinforcement thread series. The thread series has a thread (3) alternatively passing from a side of the panel to another side of the panel without passing through the other panel or the panels of the former sub-stack. The latter sub-stack of panels is arranged between the former sub-stack of panels and the side turned towards the outside of the unit. The panels of one of the sub-stacks are made of an aramid fiber fabric such as Kevlar(RTM: light, strong para-aramid synthetic fiber) and Twaron(RTM: very strong, light para-aramid fiber) fabric. |
