SBIR PHASE I: Validation of Remotely Powered and Interrogated Microwire Temperature Sensors for Composites Cure Monitoring and Control

小型企业创新研究(SBIR)第一阶段项目将完善由无线读取器组成的温度传感系统，该读取器能够远程、同时询问多个唯一识别的非晶微丝温度传感器，这些传感器可以永久地嵌入碳纤维层下面。由于没有实用的无线温度传感器，目前的碳纤维增强聚合物(CFRP)复合材料的制造方法不能从厚壁零件的关键内部实时反馈温度。该项目的结果将有助于更好地理解这种复合材料固化传感系统，以及一种新的高压罐控制系统。商用飞机行业对CFRP复合材料的使用迅速扩大，推动了市场对固化工艺改进的需求。因此，航空航天公司和供应商是微丝温度传感系统及其增强型固化控制系统商业化的直接目标。微丝增强固化工艺速度的预期改进也可能加速CFRP复合材料在汽车工业中的使用。此外，它们极低的热质量和由此产生的快速热响应将使采用实时反馈的复合材料固化设备变得更快，例如用于初始固化的微波炉和用于修复固化的感应加热器，进一步加快全球CFRP复合材料的使用。

The Small Business Innovation Research (SBIR) Phase I project will refine a temperature sensing system comprised of a wireless reader capable of remote, simultaneous interrogation of multiple, uniquely identified amorphous microwire temperature sensors that can be embedded permanently beneath layers of carbon fiber. Current manufacturing methods for carbon fiber reinforced polymer (CFRP) composites do not employ real time temperature feedback from the critical interior of thick parts because no practical wireless temperature sensors exist. The results from this project will contribute to a better understanding of this sensing system for composites curing, as well as a new autoclave control system. The commercial aircraft industry's rapidly expanding use of CFRP composites is driving marketplace demand for curing process enhancements. Thus, aerospace companies and suppliers are immediate targets for commercialization of the microwire temperature sensing system and its resultant enhanced curing control system. Anticipated improvements to the speed of microwire-enhanced curing processes may also accelerate the use of CFRP composites within the automobile industry. Furthermore, their extremely low thermal mass and resultant fast thermal response should allow faster composite curing devices employing real time feedback, such as microwave ovens for initial cure and induction heaters for repair cure, further speeding global CFRP composites use.
