Overview
The aim of this work was the complete characterisation of innovative prepreg systems based on carbon fibres and nanoparticle modified resins. After the test specimen production well known and long-time approved mechanical test methods related the aircraft industry, as well as thermo-mechanical and chemical analyses were used for the characterisation. Regarding the fibre-matrix adhesion a novel test method was developed which is based on a tensile test for single fibres. Considering the long-time experience in harmonising test methods for fibres and the experience of testing single natural, synthetic and high performance fibres a pull out test with a so called Dia-Stron equipment was feasible resulting in a very simple and standarDised test method to determine the fibre matrix adhesion.
