Manufacturing, Structural Characterisation and Mechanical Testing of
Composites
NTUA for the last six months worked in WP3: Characterisation and Testing of Performance, on the
manufacturing of composites with carbon fibre fabrics that have undergone different surface treatments
(e.g. plasma from POLITO, electropolymerisation with PMAA from NTUA, etc), through the vacuum
infusion tecnique. After the manufacturing of the composites, NTUA evaluated the structural
characteristics with micro computed tomography analysis. Then, mechanical testing in macro-scale took
place; tensile testing, as well as bend and shear testing. The results revealed that Atmospheric Plasma
treatment (APP) by POLITO, offered increased tensile properties, while PMAA on the CFs led to increased
interlaminar shear strength.
