反应性粒子代表了一个可定制的热源，用于连接应用，因为每个反应性粒子都能够进行放热，自我维持的反应。微波被用来均匀地引发该反应，并允许产生的温度-时间分布受到影响。在不同的颗粒结构、活化能和产生的最高温度之间建立因果关系的可能性，对于开发资源高效、量身定制的生产工程热源至关重要。活性镍和铝颗粒的反应产生热量，因此在几毫秒内温度可达1500 K。尽管发射率未知，但光纤传感器是一种很有前途的温度测量方法。这些具有高帧率，紧凑的设计，耐高温以及抗电磁波。在本文中，研究使用再生光纤布拉格光栅（RFBG）作为一种新的，创新的方法来表征反应性粒子。红外相机和RFBG的实验研究表明，RFBG在暴露于微波和高温下仍能保持其功能。基于RFBG记录的温度变化与红外热成像数据的良好一致性证实了RFBG作为一种复杂的表征方法和确定活性金属颗粒发射率的适用性。
Reactive particles represent a customisable heat source for joining applications as each reactive particle is able to undergo an exothermic, self-sustaining reaction. Microwaves are used to homogeneously initiate this reaction and allow the resulting temperature-time profiles to be influenced. The possibility to derive cause-effect relationships between the different particle structures, the activation energy, and the resulting maximum temperatures is essential for developing a resource-efficient, tailored heat source in production engineering. The reaction of reactive nickel and aluminium particles generates heat and thus temperatures up to 1500 K within milliseconds. A promising temperature measurement method despite an unknown emissivity are optical fibre sensors. These feature high frame rates, a compact design, and resistance to high temperatures as well as to electromagnetic waves. In this paper, the investigation of the use of regenerated fibre Bragg gratings (RFBG) as a new, innovative approach to characterise reactive particles is described. Experimental studies with an infrared camera and RFBG demonstrated that RFBG retain their functionality while being exposed to microwaves and high temperatures. The good accordance of the recorded RFBG-based temperature evolutions with infrared thermography data confirmed the suitability of RFBG as a sophisticated characterisation method and for determining the emissivity of reactive metal particles.
