Abstract
An elongate metal body, for instance an aluminium rod, with a chosen cross-sectional form manufactured by extrusion. It is a first object of the invention to make an elongate metal body stiffer and stronger without this entailing an increase in weight. In respect of this objective the metal body according to the invention has the feature that the body has at least one cavity extending at least to a considerable degree in longitudinal direction, in which cavity is received a pre-manufactured elongate reinforcing rod, of which at least the ends are coupled to the body in force-transmitting manner.
Claims22
An article of manufacture, comprising:
- an elongate metal body of a chosen cross-sectional form, the body having at least one cavity of a chosen cross-sectional geometry extending substantially in a longitudinal direction;
- and
- a pre-manufactured elongate reinforcing rod received in the at least one cavity;
- wherein the reinforcing rod is connected to the body by glue;
- wherein the reinforcing rod is connected to the body substantially along its entire outer surface;
- and
- wherein the glue has a plurality of particles added thereto.
A method of forming an article of manufacture, comprising the steps of:
- extruding an elongate metal body of a chosen cross-sectional form, the body having at least one cavity of a chosen cross-sectional geometry extending substantially in a longitudinal direction;
- positioning an elongate reinforcing rod in the at least one cavity by co-transport with the extruded body;
- and
- providing glue in the at least one cavity;
- wherein the reinforcing rod is connected to the body in a force transmitting manner;
- and
- wherein the reinforcing rod is completely embedded and sealed in the at least one cavity.
An article of manufacture, comprising:
- an elongated metal body of a chosen cross-sectional form, the body having at least one cavity of a chosen cross-sectional geometry extending substantially in a longitudinal direction;
- and
- a pre-manufactured elongate reinforcing rod received in the at least one cavity;
- wherein the reinforcing rod is connected to the body in a force transmitting manner, and wherein the reinforcing rod is connected to the body substantially along its entire outer surface, and wherein the reinforcing rod is compressed of a bundle of longitudinally extending, continuous fibers embedded in a plastic matrix and wherein the continuous fibers include carbon fibers.
A article of manufacture, comprising:
- an elongate metal body of a chosen cross-sectional form, the body having at least one cavity of a chosen cross-sectional geometry extending substantially in a longitudinal direction;
- and
- a pre-manufactured elongate reinforcing rod received in the at least one cavity;
- wherein the reinforcing rod is connected to the body in a force transmitting manner, and wherein the reinforcing rod is connected to the body substantially along its entire outer surface and wherein the reinforcing rod fits into the cavity with a small clearance to allow the substantially complete embedding of the rod by glue.
An article of manufacture, comprising:
- an elongate metal body of a chosen cross-sectional form, the body having at least one cavity of a chosen cross-sectional geometry extending substantially in a longitudinal direction;
- and
- a pre-manufactured elongate reinforcing rod received in the at least one cavity;
- wherein the reinforcing rod is connected to the body in a force transmitting manner, and wherein the reinforcing rod is connected to the body substantially along its entire outer surface and further including biasing means for holding the reinforcing rod under longitudinal bias.
An article of manufacture, comprising:
- an elongate metal body of a chosen cross-sectional form, the body having at least one cavity of a chosen cross-sectional geometry extending substantially in a longitudinal direction;
- and
- a pre-manufactured elongate reinforcing rod received in the at least one cavity;
- wherein the reinforcing rod is connected to the body in a force transmitting manner, and wherein the reinforcing rod is connected to the body substantially along its entire outer surface and wherein the reinforcing rod is received in the at least one cavity under fixed bias.
