Abstract

A re-enforced composite sheet piling segment is disclosed. The segment of sheet piling includes multiple panels. The panels of the segment come together at an angle to form a corner. A re-enforcement is placed in the corner of the segment. The re-enforcement has a cross-sectional area that is convex shaped.

Claims (20)

1. A segment of seawall sheet piling, comprising:

a polyurethane based material;

a woven pattern matrix of fibers that re-enforce the polyurethane based material; and

where the segment of seawall sheet piling is formed by pultrusion in the shape of multiple sheet piling segments that fit together at angles that are re-enforced with a convex cross-sectional shaped re-enforcement.

2. The segment of claim 1 , where the polyurethane based material is a single component material.

3. The segment of claim 1 , where the polyurethane based material is a multi-component material.

4. The segment of claim 3 , where the multi-component material comprises:

a hardening catalyst, and

a resin.

5. The segment of claim 4 , where the hardening catalyst is isocyanate.

6. The segment of claim 4 , where the resin is polyurethane.

7. The segment of claim 1 , where the polyurethane based material is heat cured.

8. The segment of sheet piling of claim 1 , where the fibers are glass.

9. A segment of sheet piling, comprising:

a fiber re-enforced polymer material;

a matrix of fibers that re-enforce the fiber re-enforced polymer material; and

a water resistant coating that is applied to the surface of the segment.

10. The segment of claim 9 , where the gel-coating is neopental isothalic acid resin.

11. The segment of claim 9 , where the matrix is a woven pattern.

12. The segment of claim 9 , where the fibers are glass fibers.
