Definitions
- the invention relates to an electrically-powered motor vehicle floor architecture, and a method for implementing thermal protection of an acoustic protection trim and trim included in such an architecture.
- the object of the invention is to propose an architecture making it possible to protect the lining while taking into account the constraints mentioned above.
- the invention proposes an electrically powered motor vehicle floor architecture comprising successively, from bottom to top:
- said architecture further comprising a fibrous and porous thermal protection layer arranged between said trim and said sheet, said protective layer comprising:
- thermal protection fibers based on at least one fusible material
- the reference to the maximum melting point of the protective fibers is used to take into account the case where the protective fibers have two melting points - like the bi-component fibers explained later -, or even the case of a mixture of protective fibers of different melting points.
- the fact of arranging a thermal protection layer below the lining makes it possible to protect it from overheating, this by means of the fusion of the thermal protection fibers.
- melting corresponds to an endothermic phase change; therefore, part of the heat released by the battery is devoted to melting the protective fibers, which makes it possible to limit the amount of heat transmitted to the lining.
- thermal protection can be reconciled with the constraints mentioned above:
- the invention proposes a method for implementing thermal protection of an acoustic protection and cladding trim included in such an architecture.
- FIG.1 is a schematic representation in partial section of an architecture according to one embodiment
- FIG.2 is a schematic cross-sectional representation of a bi-component fiber.
- an architecture 1 of the floor of an electrically powered motor vehicle comprising successively, from bottom to top:
- thermal protection fibers based on at least one fusible material
- the floor sheet 2 faces the cover 4 with the interposition, according to the embodiment shown, of an elastically compressible intermediate layer 8 of decoupling - for example based on foam - or even an air gap, according to an embodiment not shown.
- the lining 6 may for example comprise, according to the embodiment shown, a layer of covering material 9 - such as a carpet - and an elastically compressible decoupling layer 10 - in particular based on foam and/or fibers.
- the protective fibers are, at least in part, of the single-component type, said fibers being based on a single fusible material, for example polypropylene, polyamide or polyethylene terephthalate.
- the protective fibers are, at least in part, of the two-component type 11, said fibers comprising a sheath 12 based on a first fusible material and a core 13 based on a second fusible material, the melting point of said first material being lower than that of said second material, said sheath ensuring following its melting - for example at the as a result of thermocompression - the connection between the fibers of the protective layer 7.
- melting of the sheath 12 can be observed only in the event of a moderate rise in temperature, or else successively of said sheath and then of the core 13 in the event of a greater rise in temperature.
- the protective layer 7 comprises at least two types of protective fibers that melt at different temperatures, so as to allow melting of said layer in stages.
- the most temperature-resistant fibers remain intact and therefore contribute, with the structural fibers, to the structure of the protective layer 7.
- the resistance to the passage of air of the protective layer 7 is less than 6000 Nsm -3 , being for example between 3000 and 4000 Nsnr 3 , which makes it possible to ensure acoustic absorption and limits the negative influence of a high Young's modulus on acoustic protection performance.
- the Young's modulus in compression of the protective layer 7 is greater than 35 MPa, which makes it possible to ensure satisfactory lift.
- the thermal conductivity of the protective layer 7 between ⁇ 40 and +45° C. is between 0.03 and 0.12 W.m′ 1 .K′ 1 .
- the protective layer 7 is monolayer, the protective fibers - whether of one or more types - and structural fibers being mixed together.
- the protective layer 7 comprises a plurality of sub-layers 7a, 7b each comprising protective fibers mixed with structural fibers.
- the architecture 1 further comprises a thermal insulation layer, for example based on cork, placed between the sheet 5 and the protective layer 7, which makes it possible to reinforce the thermal protection.
- a thermal insulation layer for example based on cork
- the protective layer 7 has a thickness of between 4 and 8 mm.
- the protective layer 7 is needled.
- the protective layer 7 has undergone a hot compression operation, certain areas - for example "basements" - may have been subject to overcompression, to increase their lift.
- the percentage by mass of the protective fibers 7 is between 60 and 90% by mass of said layer.
- a method for implementing thermal protection of a trim 6 for acoustic protection and trim included in the architecture 1 is described, said trim being intended to be placed on a sheet metal 5 of the floor of said vehicle, said method providing for placing, between said sheet and said lining, a fibrous and porous thermal protection layer 7 comprising:
