Abstract

A self-confining structural article includes a ceramic matrix with a reinforcement member disposed within the ceramic matrix. The reinforcement member is continuous, and has a mesh with holes not exceeding 4 mm in size.

First claim

The invention claimed is:

1. A self-confining structural article comprising:
a ceramic matrix having an outer surface; and
a reinforcement member disposed within and adjacent to the outer surface of the ceramic matrix, the reinforcement member having a fabric mesh with holes that are less than or equal to 4 mm and a convex side wherein the reinforcement member is a biconical, braided reinforcement member and is encapsulated in a magnesium concrete matrix to form a column having a longitudinal axis about which the biconical, braided reinforcement is concentrically configured.

2. The self-confining structural article of claim 1 , wherein the reinforcement member is a cambered tubular shape with a ratio of a center cross sectional area to an end cross sectional area between 0.1 and 1.0.

3. The self-confining structural article of claim 1 , further comprising at least one fastener connecting the reinforcement member with at least one additional reinforcement member.

4. The self-confining structural article of claim 1 , wherein the reinforcement member contains two types of fibers.

5. The self-confining structural article of claim 1 , wherein the reinforcement member includes parallel fibers, fiber bundles, or strands are laid in differing orientations and stitched together in an interlocked reinforcement pattern which transfer force in multiple axes under loading.

6. The self-confining structural article of claim 1 , wherein the reinforcement member is non-corroding.

7. The self-confining structural article of claim 1 , further comprising a flexible reinforcement member having at least one coating.

8. The self-confining structural article of claim 1 , further comprising a frame surrounding the reinforcement member and having a periphery with opposed and spaced apart sides, the reinforcement member connected in at least two places of the frame forming a pre-form.

9. The self-confining structural article of claim 8 , wherein the reinforcement member comprises a pre-stressing member.

10. A self-confining structural article comprising:
a ceramic matrix having an outer surface;
a flexible reinforcement member having a fabric mesh with holes that are less than or equal to 4 mm and a convex side, disposed within and adjacent to the outer surface of the ceramic matrix wherein the flexible reinforcement member has a biconical shape that is continuously and smoothly cambered inward from its ends toward a center of the flexible reinforcement member such that the reinforcement member rolls upon itself when a downward force is applied; and
a retainer bracket placed around the flexible reinforcement member with portions of the retainer bracket extending to the outer surface of the ceramic matrix.

11. The self-confining structural article of claim 10 , wherein the flexible reinforcement member is a tubular shape with a ratio of a center cross sectional area to an end cross sectional area between 0.1 and 1.0.

12. The self-confining structural article of claim 10 , wherein the flexible reinforcement member is a curved sheet.

13. The self-confining structural article of claim 10 , wherein the flexible reinforcement member comprises a pre-stressing member.

14. The self-confining structural article of claim 10 , further comprising a reinforcement member having at least one coating.

15. The self-confining structural article of claim 10 , further comprising a frame surrounding the flexible reinforcement member, having a periphery with opposed and spaced apart sides, having reinforcement members connected in at least two places forming a pre-form.

16. The self-confining structural article of claim 1 wherein the reinforcement member further includes a concave side.

17. The self-confining structural article of claim 1 wherein the reinforcement member further includes a planer side.

18. A self-confining structural article comprising:
a ceramic matrix having an outer surface; and
a reinforcement member disposed within and adjacent to the outer surface of the ceramic matrix, the reinforcement member having a fabric mesh with holes that are less than or equal to 4 mm and a convex side wherein the reinforcement member has a biconical shape that is continuously and smoothly cambered inward from its ends toward a center of the reinforcement member such that the reinforcement member rolls upon itself when a downward force is applied.

19. The self-confining structural article of claim 18 , wherein the reinforcement member is a cambered tubular shape with a ratio of a center cross sectional area to an end cross sectional area between 0.1 and 1.0.

20. The self-confining structural article of claim 18 , further comprising at least one fastener connecting the reinforcement member with at least one additional reinforcement member.

21. The self-confining structural article of claim 18 , wherein the reinforcement member contains two types of fibers.

22. The self-confining structural article of claim 18 , wherein the reinforcement member includes parallel fibers, fiber bundles, or strands are laid in differing orientations and stitched together in an interlocked reinforcement pattern which transfer force in multiple axes under loading.

23. The self-confining structural article of claim 18 , further comprising a flexible reinforcement member having at least one coating.

24. The self-confining structural article of claim 18 , further comprising a frame surrounding the reinforcement member and having a periphery with opposed and spaced apart sides, the reinforcement member connected in at least two places of the frame forming a pre-form.
