Developing CFRP components for machine tools

Fig. 5: Displacement in static and dynamic case at 1st Eigen frequency
for different fibre layups (experimental validation pending)

-	 Static displacement (frequency of excitation = 0 Hz)	
- 21%
-	 Dynamic displacement at 1st Eigen frequency 	
- 56%
However, it should be noted that these results were simulated using
non-experimentally validated material cards.

Conclusions
In summary, these investigations underline that the simulation
and optimization of CFRP structural components within a milling machine can be automated, resulting in improved simulation
performance and reduced human-computer interaction. This enables a more efficient and sustainable design process. The design of
CFRP machine tool structures can be further accelerated by basic
research with the following targets:
-	 Benchmark of different beam concepts based on filament winding, hand lamination as well as gluing profiles and sheets for a
slider regarding the integration of guiding elements, stiffness per
mass and costs.
-	 Benchmark of joining technologies such as gluing, co-curing,
bolts or cones regarding static and dynamic stiffness at specific
load cases.
-	 Appropriate material models for high-modulus CFRP laminates
for the advanced simulation of the modal behaviour of CFRP
structures.
