Composites manufacturing faces increased requirements for precision, efficiency and sustainability, yet traditional process monitoring methods often fail to meet the challenges presented by complex geometries or dynamic processes. SensXPERT, operating within Netzsch Process Intelligence GmbH (Selb, Germany) is introducing high-frequency dielectric analysis (HF-DEA) technology, which is said to break these barriers, offering a contactless solution for real-time monitoring of curing behavior and flow front in composite structures.
This portable, standalone device requires no coupling media or embedded sensors, making it ideal for hard-to-reach applications such as hydrogen pressure vessel curing, infusion processes and patch repairs in aviation. It enables accurate measurements through composite layers up to 40 mm thick. From large-scale composite parts to infusion processes, HF-DEA can detect defects such as dry spots and air gaps, ensuring consistent quality and reducing material waste.
The production of hydrogen storage vessels often involves curing in high-temperature ovens where direct monitoring is impractical. According to sensXPERT, HF-DEA reduces unnecessary safety margins by providing real-time data, shortening cycle times while maintaining the integrity of these critical components.
Moreover, aircraft maintenance and repair demand the highest levels of precision. HF-DEA offers a portable, contactless solution for guaranteeing proper curing during patch repairs, improving safety and reliability.
HF-DEA is both a technological breakthrough and a sustainability enabler. By reducing curing times and optimizing energy use, it can, for instance, lower the carbon footprint of hydrogen pressure vessel production by up to 20%. Its integration into various industries, from aerospace to renewable energy, highlights its market potential and versatility.
