This invention discloses a beaded cobalt-doped Bi 25 FeO 40 The preparation method of / BiFeO3 nanofiber microwave absorbing material involves obtaining a precursor through a static method, then adding it together with bismuth nitrate, ferric nitrate, and a spinning aid into a mixed solvent composed of N,N-dimethylformamide and anhydrous ethanol to obtain a spinning solution. The spinning solution is then spun using electrospinning technology to obtain a nanofiber membrane. Finally, the material is obtained after drying and calcination. This microwave absorbing material increases the multiple reflections and scattering of electromagnetic waves, improving electromagnetic wave absorption performance. Furthermore, the heterogeneous interface formed after the two-phase composite further increases the interfacial polarization loss, resulting in a minimum reflection loss of -56.01 dB at a thickness of 2.33 mm and an effective absorption bandwidth of 6.32 GHz, covering the entire Ku-band.

The application discloses a high-reliability interface construction method for self-healing material additive manufacturing, and belongs to the technical field of metal matrix composite material additive manufacturing. The method comprises the following steps: firstly, memory alloy fibers are processed into a string bead shape through selective local etching to form a periodic "thick section-thin section" alternating structure; secondly, nanosecond pulse laser is used to construct a periodic micron groove on the surface of the fiber; and finally, the multi-scale structured fiber is combined with an aluminum-lithium alloy through laser melting deposition under the protection of argon. The molten aluminum-lithium alloy penetrates into the micron groove and coats the thick section under the capillary action, and after solidification, a "macro mechanical anchoring" and "micro mechanical hooking" double interlocking interface is formed. The method starts from physical structure design, and realizes stable and high-strength interface bonding between the aluminum-lithium alloy and the memory alloy without complex metallurgical regulation.
