Abstract

A vehicle body may have an internal skeleton, and a skin formed over the internal skeleton. The skin may include a matrix material, and a plurality of continuous fibers encased within the matrix material. At least one of the plurality of continuous fibers is in tension and has differing levels of tension along its length.

First claim

What is claimed is:

1. A vehicle body, comprising:
an internal skeleton; and
a skin formed over the internal skeleton, the skin including:
a matrix material; and
a plurality of continuous fibers encased within the matrix material, wherein at least one of the plurality of continuous fibers is in tension and has differing levels of tension along its length;

wherein the internal skeleton forms a wing shape; and
wherein the plurality of continuous fibers curve from a base end near a fore/aft center of the wing shape outward toward leading and trailing edges of the wing shape at a tip end.

2. The vehicle body of claim 1 , wherein the plurality of continuous fibers are oriented in a plurality of different directions.

3. The vehicle body of claim 2 , wherein each of the plurality of continuous fibers is in tension and has differing levels of tension along its lengths.

4. The vehicle body of claim 1 , wherein a density of the plurality of continuous fibers is greater at the base end than at the tip end.

5. The vehicle body of claim 1 , wherein the matrix material includes multiple types of resins deposited at strategic locations along lengths of the plurality of continuous fibers in the skin.

6. The vehicle body of claim 5 , wherein:
the multiple types of resins includes:
a flexible resin at a trailing edge of the wing shape; and
an acrylated resin used away from the trailing edge.

7. The vehicle body of claim 5 , wherein:
the multiple types of resins includes:
a pyrolized resin at a leading edge of the wing shape; and
an acrylated resin used away from the leading edge.

8. A vehicle body, comprising:
an internal skeleton; and
a skin formed over the internal skeleton, the skin including:
a plurality of matrix materials positioned at different location on the internal skeleton, the plurality of matrix materials including an acrylated epoxy and at least one of a flexible resin and a pyrolized resin; and
a plurality of continuous fibers encased within the matrix material, wherein at least one of the plurality of continuous fibers is in tension and has differing levels of tension along its length;
wherein the internal skeleton forms a wing shape; and
wherein the plurality of continuous fibers curve from a base end near a fore/aft center of the wing shape outward toward leading and trailing edges of the wing shape at a tip end.
