Abstract

A three-dimensional rib for a crash test dummy includes at least two layers of a band material and a layer of damping material sandwiched in between the at least two layers of the band material.

Claims

1. A three-dimensional rib for a crash test dummy comprising:

at least two layers of a band material; and

a layer of damping material sandwiched in between said at least two layers of said band material.

2. A three-dimensional rib as set forth in claim 1 wherein said band material is FDM Thermoplastics or Polyjet Photopolymers.

3. A three-dimensional rib as set forth in claim 1 wherein said damping material is FDM Thermoplastics or Polyjet Photopolymers.

4. A three-dimensional rib as set forth in claim 1 wherein said band material has a thickness of approximately 4.0 millimeters.

5. A three-dimensional rib as set forth in claim 1 wherein said damping material has a thickness of approximately 9.5 millimeters.

6. A method of making three-dimensional rib for a crash test dummy, said method comprising the steps of:

providing a three-dimensional printer;

making a CAD model of the rib for the crash test dummy;

printing, by the three-dimensional printer, the rib with at least two layers of a band material and a layer of damping material sandwiched in between the layers of the band material.

7. A method as set forth in claim 6 wherein said band material is FDM Thermoplastics or Polyjet Photopolymers.

8. A method as set forth in claim 6 wherein said damping material is FDM Thermoplastics or Polyjet Photopolymers.

9. A method as set forth in claim 6 wherein said step of printing comprises printing the at least two layers of the band material and the layer of the damping material in one printing.

10. A method as set forth in claim 6 wherein the damping material has a thickness of approximately 9.5 millimeters.

11. A method as set forth in claim 6 wherein each of the layers of band material has a thickness of approximately 4.0 millimeters.

12. A rib cage assembly for a crash test dummy comprising:

a plurality of three-dimensional ribs;

each of said ribs having at least two layers of a band material and a layer of damping material sandwiched in between said at least two layers of the band material.

13. A rib cage assembly as set forth in claim 12 wherein said band material is FDM Thermoplastics or Polyjet Photopolymers.

14. A rib cage assembly as set forth in claim 12 wherein said damping material is FDM Thermoplastics or Polyjet Photopolymers.

15. A rib cage assembly as set forth in claim 12 wherein said band material has a thickness of approximately 4.0 millimeters.

16. A rib cage assembly as set forth in claim 12 wherein said damping material has a thickness of approximately 9.5 millimeters.

17. A crash test dummy comprising:

a body;

a rib cage assembly operatively attached to said body;

said rib cage assembly including a plurality of three-dimensional ribs, each of said ribs having at least two layers of a band material and a layer of damping material sandwiched in between the at least two layers of the band material.

18. A crash test dummy as set forth in claim 17 wherein said band material is FDM Thermoplastics or Polyjet Photopolymers.

19. A crash test dummy as set forth in claim 17 wherein said damping material is FDM Thermoplastics or Polyjet Photopolymers.

20. A crash test dummy as set forth in claim 17 wherein said band material has a thickness of approximately 4.0 millimeters.

21. A crash test dummy as set forth in claim 17 wherein said damping material has a thickness of approximately 9.5 millimeters.
