동절기 낙상사고 예방을 위한 발열매트의 환경 및 운용 내구성 평가

초록

There is no practical solution to pedestrian fall accidents due to icing in winter constantly occurring every year. Spraying a deicing agent such as potassium chloride is only a follow-up measure, and it takes a lot of time and has side effects such as surrounding corrosion. In addition, the buried hot wire has limitations, including low thermal efficiency and high construction and maintenance costs. A heating mat using carbon fiber film has been developed to solve this problem and has proven its effectiveness in outdoor fields. However, performance evaluation on the long-term environment and operational durability in the actual application is insufficient. Therefore, this study conducted the performance impact evaluation on the heating mat’s long-term environment and operating durability. Specifically, the durability against deterioration was tested by simulating the winter environment with an environmental chamber. A repetitive load-imparting device evaluated the durability against the load applied to the heating mat when pedestrians are using it. As a result of the experiment, the heating mat has proven excellent durability for long-term environment and operation. It can contribute significantly to improving pedestrian safety in winter when practically applied in the future.
