Patent number: 11911975Abstract: The invention provides a carbon fiber reinforced plastic electrofusion fitting and a self-monitoring method of strain for the fitting. Carbon fiber filled polymer is used to fabricate the fitting to improve the mechanical strength of the fitting. The fitting comprises an electrofusion fitting body embedded with a resistance heating wire and two terminals arranged on the electrofusion fitting body and connected to the two ends of the resistance heating wire respectively. For the self-monitoring of strain, at least one pair of electrodes are set on the surface of the electrofusion fitting. The resistance change between electrodes caused by fitting deformation due to temperature change or mechanical loading during operation can be measured, and could be further used for structural health monitoring of the electrofusion fitting. The combination of mechanical enhancement and strain sensing of the electrofusion fitting can improve the performance and reliability of plastic pipelines.Type: GrantFiled: June 21, 2019Date of Patent: February 27, 2024Assignee: ZHEJIANG UNIVERSITYInventors: Jianfeng Shi, Riwu Yao, Jinyang Zheng
