1. A method for preparing a resin-based composite material having a three-layer structure, comprising the following steps:
(1) mixing a curable resin system with aligned carbon nanotubes to obtain an aligned carbon nanotubes prepolymer, dividing the aligned carbon nanotubes prepolymer into a first prepolymer and a second prepolymer, precuring the first prepolymer to obtain a pre-cured aligned carbon nanotube sheet;
(2) mixing the curable resin system with polydopamine-coated barium titanate nanofibers to obtain a barium titanate nanofiber prepolymer, curing the barium titanate nanofiber prepolymer to obtain a pre-cured barium titanate nanofiber sheet; and
(3) soaking the pre-cured barium titanate nanofiber sheet in the second prepolymer, laying flat the soaked pre-cured barium titanate nanofiber sheet on the pre-cured aligned carbon nanotube sheet, pouring the second prepolymer on the soaked pre-cured barium titanate nanofiber sheet, and then curing to obtain the resin-based composite material having a three-layer structure.
