Manufactured carbon/epoxy composite surfaces were analysed before and after CF4 plasma treatment in order to study their wettability with the aim to master adhesion properties. Roughness and XPS surface composition on raw and plasma treated surfaces have been correlated to surface free energy measurements. The analytical tools were first validated on a flat epoxy resin before being tested and compared on rough industrial carbon/epoxy composite samples. The results reveal that these analytical techniques can be reproducible and relevant on manufactured composite for new surface treatment studies.
