extechno will launch its latest equipment ROVINGTEST which measures the most important properties of rovings all at once.
Dr. Ulrich Mörschel, CEO of Textechno, explains, “The ROVINGTEST can be used to characterise all yarns and rovings made from reinforcement fibres like carbon and glass. ROVINGTEST is worldwide the first ever commercially available multifunctional testing system to measure performance and properties of rovings either all in one or separately.”
One important group of parameters assessed by ROVINGTEST are the friction properties of rovings to metal or ceramics and the existence or generation of broken filaments, e.g. due to the contact with surfaces. Moreover, the friction from roving to roving can be measured, which is an important parameter for instance as input for precise simulations of draping and forming processes.
Dr. Mörschel continues, “Spreading behaviour and homogeneity of filament orientation can also be measured by our new testing system, the latter on carbon fibres. These are especially important in the production of organosheets and tapes. Costly and lengthy trial productions are minimised, reproducible measurement results become comparable and easily accessible for the user. ROVINGTEST hence helps to increase both, processability and the performance of the final composite.”
Dr. Michael Effing, CEO of AMAC and Senior Advisor for fibre-reinforced plastics to Textechno, adds, “The determination of characteristic values of rovings is very important for the automated processing of the final composite parts. Rovings are used in high volume applications and processes like filament winding of pipes, pultrusion of profiles and multiaxial warp knitting for wind energy rotor blades. Thermoplastic composite tapes are gaining importance and the spreading behaviour of rovings is a key to success.”
According to Textechno, ROVINGTEST is available to the market as a full testing system and as a service.
