A structurally stable, self-supporting, lightweight, impact resistant laminate which is relatively inexpensive to manufacture and particularly suitable as an insulating barrier, such as a contoured vehicle interior panel is disclosed. The disclosed embodiment includes a finish lamina, which may preferably be cloth-like or vinyl, and a substrate lamina which is preferably structurally stable and self-supporting. The substrate lamina includes a foam lamina and reinforcing scrim laminae adhesively bonded together, preferably with an thin flexible adhesive web. The thin adhesive web material preferably comprises a mesh-like material including a large strand polyester blend having adhesive dispersed therebetween. The scrim laminae preferably comprise spunbonded polyester filaments. The substrate lamina is preferably bonded to the finish lamina with a thin flexible web also. A method for making the inventive laminate is also disclosed. |

DETAILED DESCRIPTION The preferred embodiments of the laminate of this invention will now be described in relation to an improved vehicle headliner.
It will be understood, however, that the improvements in the laminate, including the improvements in structural integrity are adaptable for other applications, including other automobile interior body panels, office partitions and ceiling panels.
The improvements may also be utilized in other applications, such as wall coverings.
For ease of description, however, the present invention will be described in relation to a vehicle headliner embodiment, which is not intended to limit the application of the disclosed inventions.
The laminate of this invention preferably includes a finish lamina and a substrate lamina which supports the finish lamina.
The substrate laminate comprises a foam layer sandwiched between two scrim layers.
The substrate laminae are adhesively bonded in a face-to-face relation to each other.
Preferably, a thin flexible adhesive sheet is located between the scrim and foam laminae thereby permanently bonding the laminae together.
The adhesive sheet is lightweight and flexible and relatively inexpensive, yet forms a strong, durable bond between the laminae.
A similar adhesive sheet may also be utilized to bond the finish lamina to the substrate laminae.
The laminate of the invention herein takes advantage of its "I-beam" construction of the substrate lamina to form a structurally stable, self-supporting, and impact resistant laminate which is lightweight and inexpensive to manufacture.
The foam lamina is lightweight, flexible and deformable.
The scrim laminae are strong and durable and provide structural stability.
When bonded together, the scrim-foam-scrim laminate provides a structure which is elastically pliable, i.
e, impact resistant, yet strong and durable.
The structure is also lightweight and relatively inexpensive to manufacture.
The finish lamina provides a soft hand feel without adding an excessive amount of weight to the structure
