cost prediction
Cost-based process selection
for CFRP aerospace parts
The cost-effective production of carbon-fibrereinforced plastic (CFRP) parts in high-wage
countries is a major research goal for the
aerospace industry and academia.
With combined efforts, a software tool for cost
prediction in early design phases is being
developed to help adequate process selection
and highlight potential cost reductions.
With said limitations, the most effective way to use cost
potentials is to reduce the production costs of CFRP parts,
which can either be done through production in best-costcountries (due to the high manual labour share) or by the
use of alternative manufacturing methods and productionand cost-based general design strategies.
However, most of the potential benefits can only be
achieved when the production process is already considered in the very early design stages (see Figure 2).

D
uring the past years, an enormous amount of scientific and industrial work has been published on the
positive effects of CFRP parts on aircraft costs. As a
general conclusion, aerospace parts made out of CFRP tend
to have higher production costs than their metallic counterparts but, due to their mechanical advantages (weight,
stiffness, dynamic strength, etc.), they tend to become
more effective in TCOs (total costs of ownership) in large
aircraft because of higher payload and/or more efficient
fuel consumption. This is proven by an increasing CFRP
weight percentage on modern passenger aircrafts (see
Figure 1).
The optimization of cost-to-performance balance is the
critical part for every company competing in a highly
competitive market environment. Within the aerospace
industry though, the freedom and potential for cost optimization in part and process design are highly limited by
external influences, such as strict industrial standards, laws
and customer requirements.
