Abstract

An impact-energy tolerant method and structures for impact-energy absorption and penetration resistance are disclosed. A body comprising a body end, and a fiber band comprising supplemental attachment sites located between an inner wall and an outer wall of the body end.

First claim

The invention claimed is:

1. An impact-energy tolerant structure, comprising:
a body comprising a body end; and
a fiber band comprising supplemental attachment sites located between an inner wall and an outer wall of the body end, wherein the supplemental attachment sites comprise teeth that increase a pull out resistance of the body end, and wherein the fiber band is operable to retain an impacting object within the inner wall and the outer wall of the body end.

2. The impact-energy tolerant structure of claim 1 , wherein the fiber band is operable to absorb energy from an impact by the impacting object.

3. The impact-energy tolerant structure of claim 1 , further comprising a structural member located in a proximity to the body end, wherein the fiber band is coupled to the structural member.

4. The impact-energy tolerant structure of claim 1 , wherein the body comprises a leading edge and the body end comprises a leading edge end of the leading edge.

5. The impact-energy tolerant structure of claim 1 , wherein the fiber band comprises an ultra-high molecular weight polyethylene.

6. The impact-energy tolerant structure of claim 1 , wherein the impact-energy tolerant structure comprises at least one of: a wing, a horizontal stabilizer, a vertical stabilizer, a propeller, and a rotor blade.

7. An impact-energy tolerant structure comprising:
a body comprising a body end;
a structural member comprising a structural-member end located in a proximity to the body end; and
a fiber band comprising supplemental attachment sites and coupled to the structural-member end, wherein the supplemental attachment sites comprise teeth that increase a pull out resistance of the structural-member end, and wherein the fiber band is operable to retain an impacting object within an inner wall and an outer wall of the body end.

8. The structure of claim 7 , wherein the fiber band comprises an ultra-high molecular weight polyethylene.

9. The structure of claim 7 , wherein the fiber band is attached to the inner wall of the body end such that the inner wall is located between the fiber band and the outer wall of the body end.

10. An impact-energy tolerant method, comprising:
receiving an impacting object at a leading edge of a structure;
absorbing an impact energy of the impacting object in a fiber band embedded within the leading edge;
redistributing the impact energy of the impacting object in the fiber band embedded within the leading edge;
retaining the impacting object within the fiber band; and
resisting pull out of the leading edge using the fiber band, wherein the fiber band comprises supplemental attachment sites, wherein the supplemental attachment sites comprise teeth that increase a pull out resistance of the leading edge.

11. The impact-energy tolerant method of claim 10 , further comprising redistributing the impact energy to the structure.

12. The impact-energy tolerant method of claim 10 , further comprising redistributing the impact energy to a structural member coupled to the fiber band.

13. The impact-energy tolerant method of claim 10 , wherein the fiber band comprises an ultra-high molecular weight polyethylene.

14. The impact-energy tolerant method of claim 10 , wherein the structure comprises at least one of: a wing, a horizontal stabilizer, a vertical stabilizer, a propeller, and a rotor blade.
