Printed Conductor Paths Integrated in Fiber Reinforced Polymers


Application of digitally printed conductors on textile fabrics and integration in fiber-reinforced polymers via vacuum infusion  

  • Characteristics of the printed conductors: reproducible resistance ±2%, no changes in resistance during bending
  • No impairment of the mechanical properties of the components with integrated printed conductors   


Printed Deformation Sensor Integrated in Fiber-Reinforced Polymers


Development of a printed, passive deformation sensor/antenna for impact detection

  •  The deformation sensor/antenna is integrated into the glass fiber-reinforced polymer and can be read out wirelessly


Printed Heaters Integrated in Fiber-Reinforced Polymers


Development of printed heaters integrated into fiber-reinforced polymers

    ■ The heaters are able to melt a 2 mm ice layer of -15 °C in 6 minutes

    ■ Heating power of 2.3 W (9V, 250mA ~ 0,1 W/cm²)


Integration of solid-state LEDs, electrically contacted by printed conductors


Development of technologies to integrate standard LEDs in fiber-reinforced plastics

    ■ No heat accumulation after 8 hours running time at 0.03 W (60 % of max. LED Power, 3V, 10mA)

    ■ No damage of the LEDs during component processing


Integration of Piezo Sensors in Fiber-Reinforced Polymers


Development of technologies for the integration and polarization of piezo sensors (PZT) in fiber-reinforced polymers  

    ■ The impact can be detected over a distance of 30 cm from the PZT sensors (at 0.5 Ns)

    ■ The transit time differences of the compression pressure waves allow the localization of the impact
