For prepregs, which are orthotropic multilayered structure on the basis of glass smooth weaving fabrics, having an ordered arrangement of yarn layers and impregnated with a resin in the uncured state of polymers at plane stress state, were found the expressions for the components of the limit friction force applied to the thread families in the nodes of interweaving. They are represented by linear relations between stress in threads and compression between the textile layers.
