Abstract
The invention provides a method of manufacturing a hollow fiber reinforced structural member, in particular for air vehicles, comprising the steps of providing a first circular braiding layer, positioning a flat strengthening body comprising at least one fabric layer having warp fibers and a woof fiber against a part of the surface of the first braiding layer, providing a second braiding layer around the first braiding layer and the strengthening body, positioning the combination of the first braiding layer, the strengthening body and the second braiding layer in a mold, impregnating the combination with resin, removing the combination as impregnated with a resin from the mold.

Method of manufacturing a hollow fiber-reinforced structural member for air vehicles, comprising:
- providing a mandrel,
- providing a first circumferential braiding layer formed by braiding fibers around the mandrel,
- positioning a flat strengthening body comprising at least one fabric layer having warp fibers and woof fibers against only a part of a surface of the first braiding layer,
- providing a second braiding layer formed by braiding fibers around the first braiding layer and the strengthening body,
- positioning the mandrel and a combination of the first braiding layer, the strengthening body and the second braiding layer in a mold which completely surrounds the mandrel and the combination,
- impregnating the combination with resin, by injecting the flat strengthening body and the first braiding layer and the second braiding layer in the mold with the resin and
- removing the combination as impregnated with the resin from the mold.
