<p>A textile armature that can be used for making composite materials or parts includes a central layer containing fiber segments of a first type of synthetic material previously submitted, before shaping it into a layer, to a process imparting a permanent crimp; outer layers including a mixture of segments of chemical fibers previously submitted to a process imparting a permanent crimping, and of segments of reinforcing fibers, at least some of the segments of chemical fibers of the outer layers penetrate along a portion of their length into the central layer. First segments of chemical fibers of the outer layers are bonded at least partially between them and to the other fiber segments of the textile armature.</p> |
