Definitions
- a first peculiarity to consider is the anisotropic character of the composite materials, the character of which results that their properties, their mechanical properties in particular, are not identical in all directions, because of the presence of the reinforcing fibers composing the material.
- Such a feature requires defining a material architecture adapted to each application.
- the lower half-box comprises a bottom consisting of a monolithic composite material plate and sandwich-structure side walls consisting of two thin skins made of composite material with fiberglass reinforcement and a core constituted by an element made of foam of polymer material, or of a material with a honeycomb structure, or of a balsa-type wood.
- FIG. 5 is a schematic cross-sectional view of the frame of Figure 3, in a plane passing at one end of the structure;
- the various structural elements of the chassis are made of composite materials.
- the structure of each of the elements is furthermore defined in such a way that the parts to be subjected to stresses in the plane are constituted by simple webs of composite material, with a monolithic structure, preferably comprising a reinforcement of longitudinally oriented fibers, while the parts of an element to undergo off-plane stresses, twists for example, have a sandwich structure formed of two skins of composite material separated by a spacer element, a core, made of a filling material, preferably the lightest possible, a foam of polymeric material of PS type, PVC, PU, PET for example, or nida or a low density wood, balsa type for example ...
- the wagon chassis according to the invention consists mainly of a beam 31 which groups together the functionalities of the upper plate 1 1 and the lower box 12 of the structure of principle described above, the beam 31 being covered with a coating plate 32.
- a filler material may be furthermore integrated in the caissons 315 and 316, a material consisting of either a foam of polymer material, or a honeycomb structure material (nida), or else Balsa type wood for example.
- This material makes it possible to bind the inner skins 91 -92-93 of the lateral boxes 315-316 to one another and to the skin placed on the upper face of the plate 32.
- the lateral reinforcement elements of composite material 33 and 34 intended to reinforce the resistance to torsion and bending (longitudinal and transverse) of the frame structure according to the invention are also constituted, as the side walls of the upper half-boxes 317 and lower 318 of two skins in composite material, reinforced with glass fibers, separated by a core consisting either of foam of polymeric material or of a material with a honeycomb structure (nida), or else of balsa type wood for example.
- the body 101 of the reinforcement is extended by flanges 102 and 103 arranged with respect to the body 101 so as to facilitate the assembly of the considered reinforcing element with the wall.
- the frame structure according to the invention has the important advantage of being composed of elements having both a simple morphology and easy to assemble (faces and supports on plane faces), as well as an internal structure easy to realize. These characteristics advantageously make it easier to assemble such a structure, despite the sometimes large dimensions of the latter.
- steps 3 and 4 can be switched. Furthermore, according to the embodiments envisaged, steps 1 to 4 may be performed in a different order, 2, 3, 1, 4 or 3, 2, 1, 4 for example.
