NOVELTY - Preparing wooden composite material involves collecting a pretreated circular veneer with a circular hole in the center and with a diameter of 11 cm, preparing an activating solution A, an activating solution B, an activating solution C, an electroless copper solution, an electroless nickel solution, hollow fibers and graphene oxide grafted iron oxide, first placing the circular veneer in the activating solution A for activation, and then placing the circular veneer in the activating solution B for activation, placing the circular veneer treated in the electroless copper solution, adding the hollow fibers, and conducting the electroless copper, first placing the circular veneer treated in the activating solution C for activation, and then placing the circular veneer in the activating solution B for activation. USE - Method for preparing wooden composite material. ADVANTAGE - The method enables to prepare wooden composite material with improved magnetic loss, conductivity loss and interface polarization magnetic relaxation loss.
