Carbon Composites
Material Behaviour and Testing
The group ‘Material Behavior and Testing’ focuses on the
investigation of the material response of fiber-reinforced
polymer matrix composites.
At the testing laboratories of the LCC a broad spectrum of
state-of-the-art test methods and equipment is available,
covering thermo-analytical methods, rheology and micros-
copy, experimental methods to measure permeability and
drapeability of UD and textile preforms, as well as static
and high strain rate mechanical testing.
The DeMAnD project as a highlight was set up to carry
out a mechanical material characterization program to
deliver a dynamic material property data base for typical
aircraft materials, with a special focus on seat and crash
absorbing structures of small aircraft. For a number of
aluminum and steel alloys, fiber-reinforced polymer matrix
composites and foam materials, dynamic tests will be
carried out over a wide range of strain rates, ranging from
quasi-static loading up to high strain rates of 500 s-1. The
project brings together renowned experts in the areas
of test method development, static and dynamic testing
of aircraft materials and structures as well as simulation
and design of aeronautical crashworthiness structures.
For each strain rate regime, the optimal test equipment
was identified and is available within the consortium.
The equipment ranges from standard universal testing
machines (quasi-static loading) to special servo-hydrau-
lic high speed testing machines (medium strain rates)
to split-Hopkinson bars (high strain rate testing). This
ensures the determination of high quality material data
and complete stress-strain curves from static up to high
strain rate loading, allowing the derivation of the strain
rate dependent material behavior for all material properties
needed for predictive crashworthiness simulations.

Additionally the LCC is participating in Solvay’s AM Cup
and has been chosen as one of eleven finalists from all
over the world. The AM Cup is a competition for process-
ing new PEEK materials comparing maximum achievable
mechanical properties, freedom of design, detailing and
testing capabilities. Through the AM Cup, Solvay aims to
find an institute capable of advancing their research to
further industrial impact.
Team Hybrid Materials and Structures –
LCC Winner of JEC Innovation Award
Forward Engineering GmbH has applied on behalf of a
project consortium consisting of KraussMaffei Technolo-
gies GmbH, Alpex Technologies GmbH, DIEFFENBACHER
GMBH, SAERTEX GmbH & Co. KG, Henkel AG & Co.
KGaA, Albert Handtmann Metallgusswerk GmbH & Co.
KG and the Chair of Carbon Composite (TUM) for this
year’s JEC Innovation Award for the development of a
T-RTM roof frame. The consortium has been awarded
during the JEC show in Paris in the category ‘Automo-
tive, structural’. The production of the roof frame was
demonstrated for the first time during the K 2016 with
live production in two minutes cycle time at the booth of
KraussMaffei. The result is a cost-efficient roof structure,
made of hybrid textiles in multi preform, functional resin
areas and integrated metal inserts out of one tool. The
new near-net-shape technology for shell-shaped com-
ponents is a further highlight to minimize material- and
process cost.
