▎ 摘　　要

NOVELTY - Composite material comprises a magnetic wave absorbing material, a filler with high compressibility, a polymer matrix, and a fibrous material i.e. carbon-based fibers and/or metal fibers. USE - The composite material is useful in electronic device, electromagnetic wave shielding material or device, and heat-conducting material or device for shielding, absorbing, preventing or avoiding electromagnetic radiation and in heat conduction or heat dissipation (all claimed). ADVANTAGE - The composite material has high compression rate, heat dissipation and electromagnetic shielding function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite material, comprising mixing above raw materials.
