    <title language="eng">Nanoindentation measurements of PVD coated multilayer constructions</title>
    <abstract language="eng">Carbon fibre reinforced thermoplastics (CFRP) are intensively used in lightweight&#13;
applications due to their high strength to weight ratio. In addition they offer good crash,&#13;
damping and recycling properties. On the basis of their morphology they are suitable for large&#13;
scale manufacturing processes. A major disadvantage consists of its poor hardness properties,&#13;
which is again an important requirement to realize a good erosion and wear behaviour.&#13;
Design/methodology/approach: In this work the application of orthotropic carbon&#13;
fibre reinforced polymers (PA6), with protective TiAlN coatings, produced by physical&#13;
vapor deposition (PVD), is investigated. The characterization of the coating is performed&#13;
by nanoindentation tests, roughness measurements and scanning electron microscopy.&#13;
Furthermore micro hardness tests on selected well prepared cross sections are conducted,&#13;
to compare the coating quality with established coating systems.&#13;
Findings: By applying TiAlN coating, the hardness of the CFRP samples can be increased&#13;
substantially up to 15 GPa, in comparison to the basic substrate. In addition the quality of&#13;
the coating surface can be improved significantly by plasma etching pre-treatment.&#13;
Research limitations/implications: The presented findings are preliminary results to&#13;
prove the application of a standard processed ceramic coating on new composite types&#13;
for mass production. The PVD coating process as well as the utilized testing methods are&#13;
suitable to realize hard coatings on thermoplastic CFRP. This effect can be exploited for&#13;
several lightweight applications to increase the erosion and wear resistance of composite&#13;
materials.&#13;
Originality/value: The presented results show, that ceramic coatings can be deposited&#13;
on standard thermoplastic CFRP with polyamide 6 matrix. Therewith it can be expected,&#13;
that the PVD coating process can make a essential contribution to increase the range of&#13;
applications.</abstract>
