Date Jul. 23, 1992.A reinforcement assemblage formed at least in part of continuous monofilaments of liquid crystal organic polymer or polymers, characterized by the following features: (a) the diameter Dm of the monofilaments is at least equal to 40 mu m and less than 400 mu m; (b) the tenacity Ta of the assemblage is greater than 80 cN/tex; (c) the secant tensile modulus Ma of the assemblage is greater than 2000 cN/tex; (d) at least one of the monofilaments is practically wound helically around an axis, the acute angle gamma which each monofilament makes with this axis, which is assumed rectilinear, being less than 30 DEG ; (e) the twist of each monofilament on itself is less than 10 turns per meter of assemblage. Articles reinforced by these assemblages, in particular automobile tires.</p> |
