Abstract
Skin-core structure fibers with both infrared and radar stealth, a preparation method therefor, and the use thereof are provided. The fibers are as follows: a core material of the skin-core structure fibers comprises the following raw materials in parts by weight: 10 parts of paraffin; 0.7-1.5 parts of an electromagnetic wave absorbent; and 1 part of a high-molecular polymer, wherein the electromagnetic wave absorbent is one or more of ferroferric oxide-intercalated graphene oxide, nano ferroferric oxide and carbon black, and wherein the skin-core structure fiber is obtained by spinning the core material with a skin-layer material.
