Abstract
A method of making a headliner assembly includes providing a porous member having first and second sides. A negative pressure is developed on the second side of the porous member, and particulate material is selectively deposited proximate the first side of the porous member to form a particulate layer having an outline that corresponds with a desired outline of the headliner assembly. The particulate material is drawn toward the first side of the porous member by the negative pressure developed on the second side of the porous member. The particulate layer is then thermoformed to form the headliner assembly.
