Abstract

An acoustical absorber is provided. That absorber includes a body incorporating an integral fastener. The integral fastener may take the form of a mounting aperture surrounded by a serrated margin of resilient teeth that provide a positive retention force for securing the acoustical absorber to a weld stud or other attachment point.

Claims

1. An acoustical absorber, comprising:

a body incorporating an integral fastener.

2. The acoustical absorber of claim 1 wherein said integral fastener comprises an aperture defined by a serrated margin.

3. The acoustical absorber of claim 2, wherein said serrated margin has a material density D₁ and said body adjacent said serrated margin has a density D₂ where D₁ >

D₂.

4. The acoustical absorber of claim 2, further including a reinforcing rib in said body extending concentrically around said margin.

5. The acoustical absorber of claim 4, wherein said margin includes four spaced slits defining four resilient teeth.

6. The acoustical absorber of claim 5, wherein each resilient tooth of said four resilient teeth define an equal arc of ninety degrees of said aperture.

7. The acoustical absorber of claim 4, wherein said margin includes a plurality of slits in communication with said aperture defining a plurality of resilient teeth.

8. The acoustical absorber of claim 7, wherein said body is made from a polyester fiber composite material.

9. A shock tower insulator, comprising:

a body incorporating an integral fastener that secures said body to a mounting stud with a positive retention force, wherein said positive retention force is at least 44 Newtons.

10. The shock tower insulator of claim 9, wherein said integral fastener comprises an aperture defined by a serrated margin.

11. The shock tower insulator of claim 10, wherein said serrated margin has a material density D₁ and said body adjacent said margin has a density D₂ where D₁ >

D₂ .

12. The shock tower insulator of claim 10, further including a reinforcing rib in said body extending concentrically around said margin.

13. The shock tower insulator of claim 12, wherein said margin includes four spaced slits defining four resilient teeth.

14. The shock tower insulator of claim 13, wherein each resilient tooth of said four resilient teeth define an equal arc of ninety degrees of said aperture.

15. The shock tower insulator of claim 12, wherein said margin includes a plurality of slits in communication with said aperture defining a plurality of resilient teeth.

16. The shock tower insulator of claim 9, wherein said body is made from a polyester fiber material.
