Abstract

In one step of a method of fabricating a composite tube, layers of uncured composite material may be laid over a surface. In another step, spaced-apart strips of at least one of uncured, partially cured, and completely cured composite material may be laid lengthwise over the laid layers of composite material. In still another step, the spaced-apart strips may be compacted against the layers of uncured composite material. In an additional step, the compacted spaced-apart strips and the layers of uncured composite material may be further consolidated and/or cured to form a composite tube.
