Abstract
The present invention relates to a component for an internal combustion engine of an automobile having reduced NVH properties. The component has a shell formed with a plastic composite material. The shell defines an inlet port, an outlet port, an outer surface and an inner surface. The inner surface defines an inner cavity to allow air passage to the internal combustion engine. A damping layer is disposed on the outer surface such that damping layer substantially dampens the noise emitted from the component.

A component for an internal combustion engine of an automobile having reduced NVH properties, the component comprising:
- a shell formed with a plastic composite material defining an inlet port, an outlet port, an outer surface and an inner surface, the inner surface defining an inner cavity to allow air passage to the internal combustion engine;
- and
- a metallic damping layer coated on the outer surface, wherein the metallic damping layer substantially dampens the noise emitted from the component.
The method of manufacturing a component for an internal combustion engine in an automobile having reduced NVH properties, the method comprising:
- providing a shell defining an inlet port, an outlet port, an outer surface and an inner surface;
- forming the shell from a plastic composite material;
- masking a portion of the outer surface such that the outer surface defines an unmasked portion;
- and
- applying a metallic damping layer to the unmasked portion to dampen noise emitted from the component.
