Analysis of Time-Domain Shielding Effectiveness of Lightweight Metallized Carbon Fiber Composite Chassis

Electromagnetic interference poses a significant challenge to the reliability and performance of electronic equipment, particularly in the aerospace and aviation sectors where the demand for high-performance electromagnetic shielding materials is paramount. This study introduces an innovative solution: a lightweight nickel-plated carbon fiber composite chassis, designed to meet these stringent requirements. Through comparative analysis, we prove that this composite chassis is not only comparable to traditional metal chassis in terms of time-domain shielding effect, but also close to traditional metal chassis in terms of heat dissipation capability. Notably, it achieves a substantial weight reduction of 71.43% to 76.25% compared to its metal counterparts, addressing the critical need for lighter materials in aerospace applications. The superior heat dissipation feature of the nickel-plated carbon fiber composite, quantitatively superior to conventional materials, indicates its potential to enhance the operational efficiency and safety of aerospace electronics. This research underscores the viability of nickel-plated carbon fiber composites as a groundbreaking material for electromagnetic shielding, promising significant advancements in aerospace and beyond.
