Abstract
A reinforced composite structure (29) is disclosed. The structure is formed by opposed layers of material extending over a core and continuous bundles stitched in a repeating pattern through the opposed layers (30, 32) and the intermediate core (28) to form the reinforced composite structural member (29).
Claims16
A stiff reinforced composite structure comprising:
- a core;
- first and second layers of fibrous material, the first and second layers bounding respective first and second opposed surfaces of the core and having respective exterior surfaces;
- and
- a first set of continuous, fibrous bundles extending in a repeating pattern
- over the exterior surface of the first layer,
- through the first layer,
- through the core;
- through the second layer,
- over the exterior surface of the second layer;
- and
- a matrix material joining the first and second layers of fibrous material, the fibrous bundles and the core into a stiff reinforced composite structure.

A method of making a stiff reinforced composite structure comprising the steps of:
- applying first and second layers of fibrous material over respective first and second opposed surfaces of a core material;
- and
- sewing a set of continuous, fibrous bundles in a repeating pattern
- over the exterior surface of the first layer,
- through the first layer,
- through the core material,
- through the second layer,
- over the exterior surface of the second layer, and
- coagulating the first and second layers of fibrous material and the fibrous bundles with a matrix material;
- and
- curing the matrix material, thereby joining the fibrous material, the fibrous bundles, the core and the matrix material into a stiff reinforced composite structure.
