With ber composites, the solutions
implemented bring the performance of each
component and that of the entire system to a new
level. Liebherr selectively substitutes conventional
materials to optimize the weight and
performance of individual components,
assemblies and complete systems. is generates
further added value in addition to the static
and dynamic performance gains. ese include
resistance to corrosion, special damping
properties and bene cial adjustable
thermal expansions.
In-house competence
Liebherr always seeks to produce components
itself including the development and manufacture
of ber composite solutions. is is how the
complete product development process takes
place– from analysis of the requirements to
selection of the materials and process through to
production on site in the Kirchdorf district of
Oberop ngen, Germany.
When the Liebherr team develops and
manufactures carbon ber-reinforced plastic
(CRP) components, it does not only make an
analysis of the customer’s application but also
considers the entire system and its environment.
From rough dimensioning to a ber-speci c
construction, Liebherr o ers a highly detailed
components analysis to optimize the ber
composite laminate. e optimal combination
based on the cost, performance and quantities is
found for every application. Liebherr relies on
automated production and modern technologies
that allow for e cient and careful processing of
raw materials. Continuous process improvement as
well as integration into the existing quality
management system ensure consistent high quality,
including in the eld of composite materials. iVT
