▎ 摘  要

NOVELTY - Preparing X-band stealth/lightning protection skin comprises laying up carbon fiber prepreg, conductive prepreg, wave-absorbing prepreg and wave-transmitting prepreg in sequence on the surface of the tooling, obtaining the first skin, where the resin matrix used in the carbon fiber prepreg, the conductive prepreg, the wave-absorbing prepreg and the wave-transmitting prepreg is the same resin matrix, and molding the first skin by a vacuum bag process. USE - The method is useful for preparing X-band stealth/lightning protection skin. ADVANTAGE - The X-band stealth/lightning protection skin relates to the field of stealth materials and solves the technical problem of poor bonding performance between the conductive layer and the stealth coating in the prior art. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for X-band stealth/lightning protection skin prepared by the above method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flow chart of the preparation method of the X-band stealth/lightning protection skin (Drawing includes non-English language text).
