The invention relates to an intelligent gasket manufacturing method based on functionalized micro-nano fiber micro-nano structured arrangement. The method comprises the following steps: putting micro-nano scale fibers into a matrix solution, and uniformly dispersing the fibers to obtain a precursor solution containing functionalized micro-nano fibers; putting the precursor solution into a gasket mold; naturally leveling the solution in the mold; applying a structured alternating-current electric field to the solution in the mold by using a signal generator and a structural interdigital electrode, so that the fibers in the solution are directionally/localizedly arranged under the action of electric field force; before the solution is solidified, introducing wires into the two ends of the mold; curing and molding the solution in a container, and completely fixing the arranged fibers and wires in a gasket; and demolding the cured material to obtain an intelligent gasket. When the intelligent gasket is applied to bolt connection and if the pre-tightening state of a bolt is changed, an output electric signal of the intelligent gasket is changed, and therefore the change of the pre-tightening force of the bolt is deduced. The method has the advantages of simple preparation process, high efficiency, accurate monitoring and the like.
