High-performance microwave absorption heating honeycomb sandwich composite with electroless nickel-plated glass fiber

This paper presents a multi-functional nickel-plated glass fiber honeycomb sandwich composite (MNHSC), a heating element that uses microwave absorption mechanisms. To design the MNHSC, a nickel-plated glass fiber was prepared using the electroless plating method to modify the thermal and electrical properties. An MNHSC with a microwave absorption performance of -22 dB at 2.45 GHz was designed to maximize its performance as a heating element by employing a coupled design method of microwave absorption and power loss density. In microwave heating experiment, the MNHSC was heated up to 160.6 degrees C within 1700 s with a microwave power of 500 W, indicating a 0.50 degrees C/s temperature increase rate to 100 degrees C. In addition, a flatwise compressive test was conducted to check their feasibility in terms of structural integrity caused by thermal effect, the results of which indicated that the proposed MNHSC could offer a promising solution for multi-functional de-icing applications.

Automated summary

This paper presents a multi-functional nickel-plated glass fiber honeycomb sandwich composite (MNHSC) as a heating element using microwave absorption mechanisms. Through design, experiments, and tests, it demonstrates that the MNHSC has excellent performance in heating and de-icing applications.
