Abstract
A composite resonator, such as for use in a vehicle air intake system, includes a fiber reinforced contacting a semi-crystalline polymer substrate. The fiber reinforced composite includes a plurality of fibers in a polymer matrix. The composite resonator further includes a particle coating contacting the fiber reinforced composite. The particle coating includes a plurality of particles deposited onto the fiber reinforced composite. In a vehicle air intake system, the composite resonator is connected to the air intake pathway. The vehicle air intake system also includes a turbocharger compressor connected to the air intake pathway.
