纤维增强塑料生产在航空和汽车以及风能行业中高速增长。另一方面，这些复合材料的生产是复杂的-因此难以自动化-并且由于大量必要的手动工作而成本密集。热固性聚合物基体的固化是工艺链中的关键步骤之一，其中工艺集成固化监测传感器可以在质量保证、工艺优化和自动化方面发挥重要作用。虽然超声波传感器非常适合用于固化监测，但在实践中-特别是在工业生产条件下-可靠性不足以用于自动化过程。代替常用的超声换能器的方法，提出了工具安装压电陶瓷代替。这些传感器的能力和效率进行了测试，固化监测传感器和集成技术和应用实例。
Fiber reinforced plastics production is growing at high rates in aeronautic and automotive as well as wind energy industry. On the other hand the production of these composite materials is complex - therefore difficult to automate - and cost-intensive due to the high amount of necessary manual work. The curing of the thermoset polymer matrix is one of the key steps in the process chain, where process-integrated cure monitoring sensors could play an important role for quality assurance, process optimization and automation. While ultrasound sensors are well suited for cure monitoring, in practice - especially in regard of industrial production conditions - the reliability is not sufficient for automated processes. Instead of the commonly used ultrasound transducers a method is presented where toolmounted piezoceramics are used instead. These sensors are tested for their capability and efficiency as cure monitoring sensors and furthermore integration techniques and application examples are presented.
