ABSTRACT:
A composite air bag assembly door is disclosed, comprising, an outer-surface layer, a flexible polyurethane foam layer, and a structural support. The polyurethane foam used in the door was designed to withstand the high tensile and tear forces generated by deployment of the air bag. The cohesive strength of the form acts as a bonding agent between the surfacing film or film and the structural support or substrate, helping to ensure that the door remains intact.
