A headliner for mounting in the passenger compartment of a vehicle is formed from a plurality of layers of materials including foamed polyurethane, fiber glass and scrim. The layers are bonded together under heat which cures an incorporated thermosetting resin. The thermosetting resin freezes the assembled laminate conforming to the configuration of the lowermost mold. After setting of the resin the flexible laminate is trimmed to the desired shape at its periphery. |

DETAILED DESCRIPTION We claim: 1.
A headliner formed from laminated layers of foamed resin, fiber glass, non-woven scrim and a decorative layer wherein, the foamed resin layer has a thickness in the range 0.
1-1.
1 inches, a layer of fiber glass is secured on each side of said foamed resin layer, each of said fiber glass layers being distributed uniformly to in an amount in the range of about 4-16 gm/ft.
sup.
2, each fiber glass layer being bonded to said foamed resin layer by a thermosetting resin impregnating said foamed resin layer and partially impregnating said fiber glass layers, said thermosetting resin being a mixture of about 50-60% by volume polyether polyol, about 40-50% by volume aromatic isocyanate and about 0.
0-0.
2% by volume catalyst and being blended such that after curing the resin impregnated foam bends rather than breaks upon deflection, one of said layers of fiber glass having a surface remote from said foamed resin, said remote surface being bonded to a non-woven layer of rayon fiber scrim by a sheet of non-porous thermoplastic resin, the other of said layers of fiber glass having a surface remote from said foamed resin, said other remote surface being bonded to a decorative layer by a sheet of thermoplastic resin.
2.
The headliner of claim 1 wherein said decorative layer is selected from the group consisting of woven fabric, porous vinyl, and non-porous vinyl.
3.
The headliner of claim 1 wherein said foamed resin layer is of open celled polyurethane having a thickness of about 1/4 inch, a density in the range of about 0.
7 to 2 pounds per ft.
sup.
3 and an ILD in the range 10-80.
4.
The headliner of claim 3 wherein both said fiber glass layers have a thickness of about 0.
2 mm.
5.
The headliner of claim 3 wherein both sheets of thermoplastic resin are of ethyleneacrylic acid copolymer.
6.
The headliner of claim 4 wherein the sheet of thermoplastic resin bonding said scrim layer to said other of the fiber glass layers is ethyleneacrylic acid copolymer and the sheet of thermoplastic resin bonding said decorative layer to one of said fiber glass layer is porous and formed of strands selected from the group consisting of polyether resin, polyamide resin or mixtures thereof
