Abstract

An assembly for managing heat and noise generated by an engine comprises a dash panel, an acoustic absorbing layer, a scrim, and a heat reflective coating. The acoustic absorbing layer comprises a plurality of fibers secure in a resin, where the acoustic absorbing layer is positioned proximate to the dash panel. The scrim is positioned proximate to the acoustic absorbing layer. The heat reflective coating comprises a polymer material and heat reflecting additives dispersed in the polymer material. The heat reflective coating is applied to the scrim as a solution of the polymer material and heat reflecting additives.

First claim

What is claimed is:

1. An assembly for managing heat and acoustic energy generated by an engine comprising:
an acoustic absorbing layer; and
a heat reflective coating secured to the acoustic absorbing layer, the heat reflective coating comprising:
a polymeric material defining a plurality of channels passing through the polymeric material; and
a plurality of heat reflecting additives deposited in the polymeric material.

2. The assembly of claim 1 , wherein the heat reflective coating is positioned between the acoustic absorbing layer and an engine.

3. The assembly of claim 2 , wherein the heat reflective coating provides for a portion of acoustic energy generated by an engine to pass through the heat reflective coating.

4. The assembly of claim 2 , wherein the heat reflective coating provides for a portion of heat generated by an engine to be redirected away from the heat reflective coating.

5. The assembly of claim 2 , wherein the heat reflecting additives are metal flakes.

6. The assembly of claim 2 , wherein the heat reflecting additives are lenticularly shaped aluminum flakes.

7. The assembly of claim 6 , wherein the heat reflecting additives are between about 10 micrometers and about 18 micrometers in diameter.

8. The assembly of claim 2 , wherein the heat reflecting additives comprises a ceramic.

9. The assembly of claim 2 , wherein the polymeric material is a thermoplastic.

10. The assembly of claim 2 , wherein the assembly further includes a flame retardant.

11. The assembly of claim 2 , wherein the heat reflective coating is formed with a thickness of between about 25 micrometers to about 150 micrometers.

12. An insulation assembly comprising:
an acoustic insulator having a first side and a second side, the acoustic insulator comprising non-woven fibers defining tortuous pathways therein, the tortuous pathways being in fluid communication with a plurality of openings on the first side; and
a heat reflective material secured to at least a portion of the first side of the acoustic insulator without sealing all openings of the plurality of openings.

13. The insulation assembly of claim 12 , wherein the heat reflective material comprises a resin and a heat reflective material.

14. The insulation assembly of claim 13 , wherein the heat reflective material is present inside the acoustic insulator at least about 25 micrometers from the first side.

15. The insulation assembly of claim 12 , further comprising a non-woven scrim defining the first side of the acoustic insulator.
