process
motion using servomotors.
The field of application can easily be widened by small modifications
of the drive shafts and different supporting tubes to fit other foam
core geometries. The winding angles can be modified through small
changes in the software used to control the electronic coupling of the
translational feed motion with the rotation drive. n

linear guide unit and the main frame is provided by a bolt.

Conclusions and outlook
The current state of the art for the production of FRP beams is a
costly and unchained manual process. The InnoBeam project intends
to establish a semi-automated solution to produce such beams.
In this paper, a manufacturing plant is planned and designed for the
semi-automated production of preforms used for carbon fibre-reinforced (CFRP) beams. The construction process is carried out according to guideline VDI 2221. These beam preforms have a maximum
size of 60 x 250 x 10,000 mm and consist of a foam core covered by
carbon fibre layers according to customer needs. During production,
this foam core is laid up with UD preforms for the chords and wound
with fibres in a ±45° orientation in order to withstand the shear
forces in the side planes. Since this foam core is not stable enough,
it is manufactured in segments and assembled on CFRP-reinforced
steel tubes. These tubes are fastened to a lightweight frame. The
frame itself enables picking up the UD chord preforms and layers of
±45° rovings are wound around the foam core. This is achieved by
electronically coupling the rotation drive with the translational feed
