Abstract

There is described a method for making a vehicle ( 2 ), including a body comprising carbon fibres, preferably a military vehicle. The method consists of the body being wound up over a mandrel with threads ( 28 ) wetted in glue. The threads ( 28 ) contain carbon fibres. The threads ( 28 ) wound around the mandrel ( 22 ) are subsequently cured. After the curing, the body is drawn off the mandrel ( 22 ), and the ends of the body are cut off at appropriate angles. Then the front end and rear end of the body are closed with closure elements, preferably closure elements containing carbon fibres and armouring materials. During the winding process, one or more layers of lightweight ceramic and/or other armouring materials ( 26 ) are laid in, which thereby become integrated in the basic body.

Claims (8)

1. A method for making a vehicle ( 2 ), including a body comprising carbon fibres ( 28 ), where the body is wound up on a rotating mandrel ( 22 ) with threads ( 28 ) from rolls of threads used simultaneously and wetted in glue, where the threads are guided through a gluing apparatus fastened to a slide being moved in parallel with a longitudinal axis of the mandrel, where the way the threads are wound around the mandrel is varied, by varying the speed of the slide relative to the rotational speed of the mandrel, thereby providing a very strong weaving with threads ( 28 ) oriented in various directions, where the threads ( 28 ) contain carbon fibres, where the threads ( 28 ) wound around the mandrel ( 22 ), are subsequently cured, where, after the curing, the body is drawn off the mandrel ( 22 ), where the front end and rear end of the body are closed with closure elements, wherein the ends of the body are cut off at appropriate angles, and that the closure elements contain carbon fibres and armouring materials and that during the winding process, one or more layers of light weight ceramic and/or other armouring materials ( 26 ) are laid in which thereby become integrated in the basic body.

2. Method according to claim 1 , further comprising adding mountings before, during or after winding the body wherein the body is subsequently surface treated.

3. Method according to claim 2 , wherein after the surface treatment of the body, mounting elements are fitted on the mountings.

4. Method according to claim 1 , wherein the vehicle ( 2 ) is a military vehicle.

5. Method according to claim 1 , wherein the vehicle ( 2 ) is an armoured military vehicle.

6. Method according to claim 1 , wherein the carbon fibers are prestressed carbon fibers.

7. Method according to claim 1 , wherein increasing speed of the slide increases angles of the threads to a plane perpendicular to the axis of mandrel.

8. Method according to claim 1 , wherein decreasing speed of the slide decreases angles of the threads to a plane perpendicular to the axis of mandrel.
