  • Patent number: 10569500
    Abstract: A method for producing an automotive equipment part includes the following steps: arranging a porous layer in a foaming mold; injection, on one side of the porous layer, of a foam precursor; expansion of the precursor material to form a foam base layer bonded to the porous layer; and extraction from the mold of the equipment part including the porous layer and the foam base layer bonded to the porous layer. The method further includes a step for injecting a pressurized fluid on a second side of the porous layer to form a counter-pressure to the expansion of the precursor material.

  • Publication number: 20170291330
    Abstract: A method for producing a composite part. The method includes the following steps: stacking a first mat, a spacer and a second mat in a heatable mold; at least one of the mats including a continuous web of fibers impregnated with a thermosetting resin; and compressing and heating of the stack by the heatable mold, in order to polymerize the thermosetting resin. The stacking step includes the deposition, in a heatable mold, of a first and a second filtration layer, in contact respectively with the first and second mats, on the opposite side from the spacer. The filtration layers are porous to steam and relatively less porous to the thermosetting resin. During the compression and heating step steam is evacuated from the mold.

  • Patent number: 9561638
    Abstract: This method includes the arrangement of a first sheet (22A) of porous material on a first face (18) of a base layer and of a second sheet (22B) of porous material of a second face (20) of the base layer before a heating step. Each sheet (22A, 22B) of porous material has a thickness of less than that of the formed layer (16). The sheets (22A, 22B) of porous material confine between them the molten polymeric material derived from the heat fusible polymer fibers during the heating step. The sheets (22A, 22B) of porous material are bound to the formed layer (16) after the step for building up the formed layer (16), in order to make up a first composite body (12A).

  • Publication number: 20160263858
    Abstract: A structural part (10) for a motor vehicle includes first (12A) and second (12B) mats, each mat comprising fibers and a resin bonding the fibers, and a separator (14) inserted between the first (12A) and second (12B) mats, the first (12A) and second (12B) mats being fixed on opposite faces of the separator (14). At least one of the first (12A) and second (12B) mats includes at least one continuous web of fibers (16), said web (16) comprising a plurality of parallel fibers bonded together by a thermosetting resin, at least part of the fibers of each web (16) having a length greater than 20 cm, in particular greater than 50 cm.

  • Patent number: 8157051
    Abstract: This method includes the placing of the first porous layer (1) onto one part of a wall of a mold cavity having the shape desired by the soundproofing component, the first layer (1) not occupying the entire cavity, and the injection of a foaming polymer composition into the cavity of the mold to form the second open-cell porous layer (3). The two steps of placing the practically airtight intermediate layer (2) onto the first porous layer (1) and of injecting a polymer composition in order to form the second porous layer (3) are carried out simultaneously in a single step of injecting the foaming polymer composition.

  • Patent number: 7789197
    Abstract: A soundproofing assembly includes stacked layers in the form of a first set of layers (36) having good resistance to the passage of air, and a second set of layers (24) with mass-spring function including a layer (28) having a heavy viscoelastic mass and a spring type layer (26); the first set of layers includes a layer (36) of a foam with open cells of high porosity, high tortuosity and good resistance to the passage of air, the layer (36) having, owing to its high tortuosity, excellent sonic absorption properties at medium and high frequencies. The invention is useful for soundproofing motor car passenger compartments.

  • Publication number: 20040150128
    Abstract: Method for producing a sound insulation component of the spring-mass type. Additions of heavy material are locally deposited on a layer of heavy material having a substantially constant thickness producing. The additions of heavy material form an excess thickness on said layer of heavy material having a substantially constant thickness, in order to form therewith a sound insulation layer having a variable thickness. Then, a resilient layer is deposited. The resilient layer forms a sound absorber on the sound insulation layer, and connecting the sound absorption layer and the sound insulation layer together.
