Abstract
A substantially metal-free exhaust subsystem includes an exterior housing formed of polymer; and a pipe formed of a layered fibers formed at least partially of glass, and bound by an inorganic binder. The fibers may be glass or ceramic, and may define micro-pores on the interior of the pipe that aid in absorbing acoustic energy, and thereby attenuating exhaust noise.
Claims19
An exhaust subsystem comprising:
- an exterior housing formed of polymer;
- a pipe carried by said exterior housing, that emits gases into said housing to attenuate sound;
- wherein said pipe is formed of a layered fibers formed at least partially of glass, and bound by an inorganic binder.
A method of forming a pipe for use in an exhaust subsystem comprising forming and curing at least one layer comprising fiber material and an inorganic binder on a molding core, and curing said inorganic binder to form said pipe.
