Abstract
Methods and systems are provided for a coupling device. In one example, the coupling device may be formed of a composite material and positioned between an exhaust system and a vehicle chassis. The composite material may include aluminum particles dispersed in an elastomer matrix to reduce an overall thermal absorptivity of the composite material.
Claims5
A vehicle, comprising:
- a chassis;
- an exhaust system arranged below the chassis;
- and
- at least one coupling device coupling the exhaust system to the chassis and formed of an aluminum particle/rubber composite with aluminum particles dispersed in a rubber matrix;
- wherein the aluminum particles, having a thermal absorptivity lower than a thermal absorptivity of the rubber matrix, are concentrated in an outer boundary region of the at least one coupling device to form a heat shielding layer at an outer surface of the at least one coupling device.
