Abstract
A laminated product (1) that forms a deformable cellular structure, comprising: an upper band (2) and a lower band (3) both oriented in the same main direction (X); and between the two bands and connecting the latter in zones (4a, 4b) referred to anchoring zones, a series (5A, 5B, 5C) that extends in the direction X, of cylindrical structures (5) referred to connecting cylindrical structures that are non-touching in the direction X. Each connecting cylindrical structure (5) comprises a plurality of preferably concentric elementary cylinders (5a, 5b) having their generatrix oriented along an axis Y perpendicular to the direction X, said elementary cylinders being fitted one inside the other and interconnected to one another in each anchoring zone (4). Said elementary cylinders are especially composite cylinders comprising fibers embedded in a resin matrix. Such a laminated product can be used as an elastic beam having a high resistance to flexural/compressive stresses and having a high endurance to such repeated or alternated stresses, in particular as a shear band in a non-pneumatic resilient wheel.
