Thermoplastic laminates usually consist of oriented fibres in thermoplastic matrices. Commonly glass fibres or carbon fibres are used as reinforcement for such laminates. The application of thin wooden sheets (veneers) as reinforcement applications is new. Therefore the bonding of such combinations has to be investigated. Various tests can be used for evaluating the bonding between the components of the laminates. The aim of this study is to determine a fast and easy method suitable for quality control of new bio-based wooden laminates.
