Abstract
A ceiling material body (1a) includes a substrate layer (2) formed from rigid urethane foam; a first fiber-reinforced layer (3) provided on an in-cabin side of the substrate layer (2); a second fiber-reinforced layer (4) provided on an out-cabin side of the substrate layer (2); a surface layer (5) provided on an in-cabin side of the first fiber-reinforced layer (3); and a back layer (6) provided on an out-cabin side of the second fiber-reinforced layer (4). The second fiber-reinforced layer (4) includes a glass paper (7) overlaying the substrate layer (2) and a glass mat (8) overlaying an opposite side of the glass paper (7) from the substrate layer (2).
Claims9
A vehicular formed ceiling material disposed on an in-cabin side of a roof panel of a vehicle and having a ceiling material body in the form of a panel, the ceiling material body comprising:
- a substrate layer formed from rigid urethane foam;
- a first fiber-reinforced layer formed through curing a first adhesive applied, and provided on an in-cabin side of the substrate layer;
- a second fiber-reinforced layer formed through curing a second adhesive applied, and provided on a roof panel side of the substrate layer;
- a surface layer bonded to an in-cabin side of the first fiber-reinforced layer using the first adhesive;
- and
- a back layer bonded to a roof panel side of the second fiber-reinforced layer using the second adhesive,
- wherein the first fiber-reinforced layer includes a first mat material obtained by accumulating randomly a number of chopped strands formed from glass filaments or basalt filaments into the shape of a mat to combine into one piece using a binder,
- wherein the second fiber-reinforced layer includes a paper material formed from glass filaments or basalt filaments, the paper material overlaying the substrate layer, and a second mat material obtained by accumulating randomly a number of chopped strands formed from glass filaments or basalt filaments into the shape of a mat to combine into one piece using a binder, the second mat material overlaying an opposite side of the paper material from the substrate layer.
