Large-scale project for the repair
of CRP-based series vehicles
Due to the increasing use of fibre-reinforced plastics (FRP)
in automotive construction, the automotive industry and
vehicle workshops are facing the challenge of providing
economic repair methods.

WTH Aachen University, in close
cooperation with seven research
institutes and around fifty industrial
companies, is currently developing new
technologies for the identification and assessment of damage. The project also covers
the customised production of repair materials - so-called patches - and the actual repair
process, including quality assurance.

FRP and CRP
The background behind this research
initiative is that new vehicle concepts are
opting increasingly for FRP, and especially
carbon-reinforced plastics (CRP), because
these materials have not only lower weight
but also very high stiffness and strength.
Due to advances in the efficiency of production plants and a reduction in cycle times,
FRP is also being increasingly used in the
large-volume series production of vehicles.
Furthermore, the pressure from legislators to reduce CO2 emissions means that
lightweight construction materials such as
composites are being deployed in ever more
vehicles.
When it comes to repairing FRP parts in
ultra-small series, the established method of
eliminating the damage is to either replace
the entire component or to repair the damage locally on the basis of expert know-how.

This method is more expensive and more
resource-intensive than repair processes for
metal structures. The replacement of large
integral structures, such as the CRP body
of an electric vehicle, is currently impossible at acceptable cost. To ensure customer
acceptance, typical repair workshops must
be enabled to assess and repair damages at
low cost.

Industry 4.0 principles
The project follows the Industry 4.0 principles: all the elements involved in value creation must be designed so that they can be
flexibly adapted to changing requirements
and be linked in such a way that they can
communicate with each other. Because of
the new approach, completely new business
models are generated, the development of
which will also be examined. The damage is
documented based on the automatic fusion
of data related to different non-destructive
testing principles. The data are evaluated

automatically and instructions are drawn
up from this to deal with the damaged area.
For the repair, repair materials in the form
of patches, adapted to the particular vehicle
and type of damage, are manufactured By
means of a system for customised mass
production. The patches are subsequently
sent to the workshop. The repair is then carried out using newly developed repair and
quality assurance processes. In the future,
suitable support systems should provide the
necessary assistance for tasks of this kind.

A collaborative project
The institutes taking part in this project
are the Institute of Plastics Processing
(IKV), the Laboratory for Machine Tools
and Productive Engineering (WZL), the
Institute of Automotive Engineering (ika),
the Institute of Welding and Joining (ISF),
the Institute of Metal Forming (IBF), the
Institute of Man-Machine Interaction
(MMI) and the Research Institute for
Industrial Management (FIR) at RWTH
Aachen University. Apart from this, around
fifty industrial companies are taking part in
a project-accompanying committee. The
project is funded for an initial period of three
years By the Confederation of Industrial
Research Associations "Otto von Guericke"
(AiF) as part of the funding competition
"Lead technologies for SMEs". n
