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.

小型企业创新研究（SBIR）第一阶段项目将改进一种温度传感系统，该系统由一个无线读取器组成，能够远程同时询问多个可永久嵌入碳纤维层下的唯一标识的非晶微丝温度传感器。碳纤维增强聚合物（CFRP）复合材料的当前制造方法不采用来自厚部件的临界内部的真实的时间温度反馈，因为不存在实用的无线温度传感器。 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，以及一种新的热压罐控制系统。商用飞机工业对CFRP复合材料的快速扩展使用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所得增强固化控制系统商业化的直接目标。对微丝增强固化过程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应允许采用真实的时间反馈的更快的复合材料固化装置，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，进一步加速全球CFRP复合材料的使用。
