Short carbon fiber is highly favored by researchers due to its high strength, high modulus, and excellent electrical conductivity. In terms of electromagnetic properties, the aspect ratio of short carbon fibers has a significant impact on their electromagnetic performance. Research has shown that the aspect ratio of short carbon fibers is directly proportional to the electromagnetic shielding performance of the material. When the length of short carbon fibers is short, the time for current to flow along the fiber length direction is too short, resulting in lower electrical conductivity, which in turn leads to lower complex dielectric constant and losses. Therefore, by regulating the length and distribution of short carbon fibers, their electromagnetic properties can be effectively improved.
