철도차량용 발열 가능 복합소재 실물시제의 발열 성능 평가 및 발열 균일도 향상 연구

초록

In the field of transportation, the application of composite materials is expanding for the purpose of reducing weight, and recently, research on multifunctionalization of composite materials through nan？materials and fusion is being actively conducted to improve competitiveness. Meanwhile, railway vehicles use an air-conditioning heating method that forcibly circulates high-temperature air, but it causes various problems such as deterioration of indo？r air quality. In this study, we developed a heating composite material for railway vehicles that can change the existing heating paradigm. Specifically, the manufacturability and applicability on a full scale were examined by inserting a carbon fiber heating element into a laminate panel and a sandwich panel, which are mainly used in railway vehicle interior materials. In addition, to improve heating uniformity, Ag coating was applied between the heating element and the electrode to improve electrical conductivity and contact, and the thermal conductivity of the heating composite material was improved by mixing a high heat dissipation material into the resin.
