Definitions

  • the method of this first embodiment utilizes a first mold component or part 32 having a first mold surface 34.
  • the first mold component 32 preferably is formulated by electrolytically depositing nickel over a rigid cast epoxy substrate which is secondarily removed at the end of the deposition/plating process to yield a self- supporting mold capable of being mounted and controlled in a tooling module.
  • the first mold surface 34 has a complementary configuration to the desired configuration of the exterior surface 10a, and is grained to define a texture that substantially complements the desired texture of the exposed portion of the outer layer 26 and simulates real leather.
  • the intermediate layer can have a thickness in a range of from about 5 mm to about 12 mm.
  • Exemplary polyisocyanates that can be selected as part of the composition 42 for forming the inner layer 28 include diisocyanates having aromatic closed-ring structures, such as diphenylmethane diisocyanate prepolymer (MDI prepolymer), which can be obtained from BASF Corp. of Wyandotte, MI. under the trade designation ELASTOLIT M50555T, ISOCYANATE, NPU U05275, or diphenylmethane-4,4'-diisocyanate (MDI), or mixed isomers of MDI or mixtures of the above, which are available from BASF or Dow Chemical Corp. of Midland, MI, Mobay (Bayer) Chemical Corp. of Baytown, Texas, or ICI America of Geismar, LA.
  • MDI prepolymer diphenylmethane diisocyanate prepolymer
  • MDI diphenylmethane diisocyanate prepolymer

  • thermoplastic polyurethane preferably contains at least one ethylenically unsaturated bond in its backbone and/or hydroxyl groups.
  • the ethylenically unsaturated bond and/or hydroxyl groups of the thermoplastic polyurethane is/are capable of reacting with the crosslinker (e.g., carbodiimide) in the outer layer 26, so that the crosslinker can successfully crosslink the polyurethane of the outer layer 26 with the polyurethane of the casting composition.
  • crosslinker e.g., carbodiimide
  • Exemplary thermoplastic polyurethanes include, without limitation, ESTANE (provided by B.F. Goodrich of Akron, Ohio) and PELLETHANE (provided by Dow Chemical Company of Midland Michigan).
  • condensation reaction between the blends of polyols and polyisocyanates releases water, which reacts with the polyisocyanate to generate carbon dioxide and thereby impart the cellular structure to the intermediate layer 30. Accordingly, a slightly stoichiometric excess of polyol can be provided to form the semi-rigid polyurethane cellular foam.

Abstract

Structure de panneau pouvant être montée dans un véhicule afin de constituer une partie de l'intérieur de ce véhicule et consistant en une structure composite stratifiée, en un substrat de renforcement et en un ou plusieurs éléments ornementaux (15, 20) tournés vers l'intérieur du véhicule. Nouveau procédé servant à fabriquer cette structure de panneau et consistant à placer ces éléments ornementaux (15, 20) sur une surface (34) de moule, chacun de ces éléments ornementaux possédant une surface extérieure tournée vers la surface (34) du moule et des surfaces restantes non tournées vers la surface du moule. On pulvérise (42) une couche extérieure mince sur les surfaces restantes des éléments ornementaux et sur des parties de la surface du moule non recouvertes par ces éléments, de manière à faire adhérer cette couche extérieure aux éléments ornementaux et à intégrer la couche extérieure à ces éléments. On applique ensuite une formulation de résine au-dessus de la surface intérieure de la couche extérieure, tandis que cette dernière se trouve sur la surface du moule, de façon à créer une couche intérieure adhérant à la couche extérieure, ces couches intérieure et extérieure constituant ensemble la structure composite stratifiée.
