The invention provides a phase change composite material capable of simulating a filter capsule function and a production method and application thereof, belongs to the technical field of the manufacturing of filter inserts in filter tips, and solves the technical problems of manufacturing costs and substance volatilization of existing cigarettes with filter capsules and common gel filter tips. The composite material comprises a hollow soft tube and sustained-release gel wrapped in the soft tube and is characterized in that the overall length of the composite material is 1/3-2/3 of the lengthof a common filter tip, and the composite material is prepared by composting the gel and the soft tube during formation. The composite material has the advantages that fragrance keeping performance can be increased, the layering of fragrant-substance volatilization can be increased, more choices are provided for consumers, and the composite material is low in production cost, high in adaptabilityto perfume and rich in product form.
