Continental Structural Plastics (CSP) is supplying Ford Motor Company with the industry’s first composite, dual-wall-dash engine shroud for use in the 2020 Ford Explorer. This sheet molded compound (SMC) advanced composite shroud significantly reduces the powertrain noise, vibration and harshness (NVH) experienced in the vehicle cabin.
Developed in collaboration with Ford using the tools in Ford’s new NVH lab, the composite engine shroud creates an air gap between the engine compartment and the steel front bulkhead by wrapping around the back of the engine and meeting the strut towers on each side of the engine bay. This composite dual-wall-dash offers a number of benefits over the all-steel components used in competitors’ luxury SUV models. Acoustically, the composite provides an improved sound barrier over competitive materials. And because it is made from composites, it offers the moldability and design flexibility needed to support a complex, under- hood packaging environment. The composite dual wall dash also:
• Reduces engine noise
• Improves acoustics by dissipating sound before it reaches the primary dash panel
• Provides superior thermal protection for electrical components
• Accommodates engine assembly and serviceability concerns
