Federal-Mogul offers a solution to difficult heat and weight-reduction challenges, as well as other engine compartment packaging challenges with its new heat-shield technology. The company’s Nimbus GII is a lightweight material that provides both high thermal efficiency and high formability for creating complex shapes for custom applications. According to Federal-Mogul, Nimbus GII is up to approximately 80% lighter than typical steel sandwich heat shields. The heat shield features a construction that interlocks two thin corrugated aluminum sheets, providing high formability and a rigid structure. An insulating air pocket between the two layers increases the inherent high thermal performance of the aluminum.
