| Summary: | In order to successfully use the strength of carbon fibres in composite applications, the fibres must be embedded into matrix materials. Usually, thermoplastic or duroplastic polymers are used to hold the flexible fibres in a form in which they can be used, to guide mechanical stress into the fibres and to protect the fibres from the distortive influences of their environment, such as friction or misaligning stress. For the strength of the composite material, the fibre-matrix-adhesion is the crucial parameter to characterize the composite’s quality and strength. Therefore, this paper shall present the need and the possibilities for different testing methods concerning fibre-matrix-adhesion.
