Abstract
A laminated material having a cross section comprising a core and at least one lateral wing, for example a cross section in the form of an I, T, J, .OMEGA. or the like is provided as a result of the impregnation of a reinforcing textile structure and the hardening of the assembly. The textile structure includes two woven laps spaced from one another and a connecting lap extending between the two laps. The material is characterized in that the connecting lap consists of at least one lap of warp binding threads trapped between the weft threads of the two woven laps.
