The layers are alternately overlapped, some with the fibers oriented substantially in a longitudinal direction, the others oriented in a substantially transverse direction, the thickness of each layer being less or at most equal to the average length of the fibers present in the layer. Preferably, the V-belt is a cogged or toothed belt.
