Abstract
The invention relates to 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.
Claims42
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 having a bundle of longitudinally-extending, continuous fibers embedded in a plastic matrix,
- wherein the reinforcing rod is received in the at least one cavity connected to the body in a force transmitting manner and completely embedded and sealed in the at least one cavity.
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
- drawing in glue to the cavity by a suction pump connected to an end of the cavity,
- wherein the reinforcing rod is connected to the body in a force transmitting manner and
- is completely embedded and sealed in the at least one cavity.
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 having a bundle of longitudinally-extending, continuous fibers embedded in a plastic matrix received in the at least one cavity,
- wherein the reinforcing rod is connected to the body in a force transmitting manner, and the rod is connected to the body substantially along its entire outer surface.
