▎ 摘　　要

NOVELTY - The method involves making and cutting the skin in advance to the needed size. The special glue film is used to make the honeycomb core material at normal temperature bonding the skin. The graphene powder material is filled with different content or different components into the core grid of the honeycomb core material. The special glue film is covered on the upper surface of the honeycomb core material, and the cured composite fiber board is placed, then assembled into the heat pressing tank to solidify, and finally graphene filling honeycomb core wave-absorbing composite material is formed. The filling graphene powder material is set to adopt manual filling or machine filling mode. USE - Preparation method of graphene-filled honeycomb core wave-absorbing stealth composite material for wearable micro-electronic device used in science and engineering field. ADVANTAGE - The graphene-filled honeycomb core wave-absorbing stealth honeycomb composite material has weight greatly reduced, at the same time, the material avoids the traditional wave absorbing material need to change frequently. The manufacturing technique of the material is simple, the control is easy, can quickly form industrial transformation. The technical process does not involve toxic and harmful operations. The method does not relate to the graphene slurry and coating layer, so that can effectively avoid the coating material related aging, cracking and other related failure problem. The graphene powder material filled in the honey comb core grid can have a set of material components or formulation, wide adjustable range, performance control limit is wide. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the blank honeycomb sample. (Drawing includes non-English language text).
