The characterisation of accurate material properties is a prerequisite for any forming simulation. Due to their characteristics, the mechanical behaviour of pre-impregnated Carbon Fibre Reinforced Polymers must be investigated under controlled environmental conditions, i.e. humidity and temperature. In this work, flexural properties in fibre direction of unidirectional thermoplastic tapes (PA6) are investigated at different temperatures using a Dynamic Mechanical Analysis system. In a first step, four different types of flexural setups are assessed (cantilevers, 3-point-bendings) with specimens of two different thicknesses at three temperatures and three loading rates. Once the most suitable test setup-specimen combination is defined, quasistatic tests are conducted in order to assess temperature and loading rate dependencies of the material.
