This type is suitable for use in door trim and B-pillars. 4.1.7 Type VII: A polyurethane elastomeric molded soft skin that consists of either an aliphatic urethane in mo
14、ld coating followed by an aromatic solid urethane skin or a solid aliphatic skin with urethane foam injected between the skin and a plastic substrate. This type is suitable for use as an instrument panel trim cover. 4.1.8 Type VIII: A thermoplastic composite of polypropylene and long glass chopped f
15、ibers. Substrate is sandwiched between outer layers of scrim and adhesive film. Composite is adhered to a foam-backed vinyl through compression molding. This type is suitable for use as headliner, back panels and B-pillars. 4.2 Performance Requirements 4.2.1 Impact Resistance Test panels mounted in
16、an appropriate fixture shall withstand a minimum impact of 3.9 J (3.0 ft/lbs) without significant damage or cracking. The sample(s) exposed in the dimensional stability test should be returned to the cold chamber at 302C (-225F) for 4 hours and tested immediately upon removal. 4.2.2 Dimensional Stab
