Method of forming a headliner

摘要

A method of forming a lap mat for use in a subsequent molding operation to form a headliner includes forming a first continuous particulate layer having a non-uniform composition; folding the first continuous particulate layer to form a plurality of first layers; and binding the first layers together wherein the first layers cooperate to define a first region having a first material composition, and a second region having a second material composition different than the first material composition.
