<p>A muffler assembly includes a housing defining at least one internal chamber. The housing is constructed from a composite material made from a thermoplastic resin and a reinforcing element. The reinforcing element is selected from a group of reinforcing materials consisting of glass fibers, aramid fibers, polyamide fibers, carbon fibers, graphite fibers, mineral fibers, ceramic fibers, carbon nanotubes, nano fillers, mineral fillers, ceramic fillers and combinations thereof. A pipe is received in the housing. The pipe includes at least one opening providing acoustic communication between an internal passage in the pipe and the chamber in the housing. An acoustic attenuating material is received in that chamber.</p> |
