Abstract

A strengthened component includes a sacrificial material mold of the component having an outer surface, an insert having an inner surface and an outer surface opposite and spaced from the inner surface such that the strengthening insert inner surface abuts the mold outer surface, and a metallic layer deposited over the exposed mold outer surface and the exposed strengthening insert outer surface, where the sacrificial material mold is removed from the strengthened component.

First claim

What is claimed is:

1. An electroformed component comprising:
a strengthening insert having a first inner surface and a first strengthening insert outer surface opposite and spaced from the first inner surface by at least one end; and
an electroformed metallic layer having a second inner surface and a second outer surface opposite and spaced from the second inner surface, the second inner surface abutting the first strengthening insert outer surface, wherein the electroformed metallic layer includes a first portion proximate the at least one end, wherein the first portion has an increased thickness compared to a second portion of the electroformed metallic layer, and wherein the electroformed metallic layer is configured to entirely cover and is fixed to the first strengthening insert outer surface.

2. The electroformed component of claim 1 , further comprising a fluid passageway.

3. The electroformed component of claim 1 , wherein the strengthening insert is located at a pre-identified high stress area.

4. The electroformed component of claim 1 , wherein the second portion of the electroformed metallic layer has a first thickness, wherein the first thickness is less than a second thickness of the strengthening insert.

5. The electroformed component of claim 1 , wherein the strengthening insert is metallic.

6. The electroformed component of claim 1 , wherein at least a portion of the first strengthening insert outer surface is metalized before the electroformed metallic layer is formed.

7. A strengthened component, comprising:
a strengthening insert having a first end, a second end, an inner surface and a strengthening insert outer surface, the strengthening insert outer surface opposite and spaced from the inner surface; and
a metallic layer fixed to the strengthening insert outer surface and having a thickened portion adjacent at least one of the first end or the second end, the thickened portion defining an increased thickness compared to another portion of the metallic layer.

8. The strengthened component of claim 7 , wherein the metallic layer entirely covers the strengthening insert outer surface.

9. The strengthened component of claim 7 , wherein the strengthening insert is disposed at a pre-identified high stress area of the strengthened component.

10. The strengthened component of claim 7 , wherein the strengthening insert is a metallic strengthening insert and wherein at least one of the first end or the second end of the strengthening insert includes at least one of a straight insert edge, a beveled insert edge, a blended insert edge, or a radial insert edge.

11. The strengthened component of claim 7 , wherein the strengthened component comprises at least one of a conduit joint, straight pipe, or an elbow.

12. The strengthened component of claim 7 , wherein the metallic layer further comprises portion having a first thickness, wherein the first thickness is less than a second thickness of the strengthening insert.

13. The strengthened component of claim 7 , wherein the metallic layer is at least 0.40 millimeters thick over the strengthening insert outer surface.

14. The strengthened component of claim 7 , wherein at least a portion of the outer surface of the strengthening insert is metalized.

15. A fluid conduit for an aircraft bleed air system comprising:
a strengthening metallic insert positioned at a pre-identified high stress area, wherein the strengthening metallic insert defines an inner surface and a strengthening metallic insert outer surface, the strengthening metallic insert outer surface opposite and spaced from the inner surface, and wherein a distance between the inner surface and the strengthening metallic insert outer surface defines a first thickness; and
an electroformed metallic layer entirely covering and fixed to the strengthening metallic insert outer surface, and the electroformed metallic layer having a first portion defining a second thickness, wherein the second thickness is less than the first thickness and the electroformed metallic layer having a second portion adjacent an end of the strengthening metallic insert and wherein the second portion has a third thickness, and wherein the second thickness is less than the third thickness.

16. The fluid conduit of claim 15 , wherein the electroformed metallic layer is at least 0.40 millimeters thick.

17. The fluid conduit of claim 16 , wherein at least a portion of the strengthening metallic insert outer surface includes a metalized layer.
