Abstract

The invention discloses a layered frame composite structure filled with energetic materials and a preparation method thereof. The sol is prepared from polysaccharide or lignin natural polymer materials, and the oriented crystallization of the solvent in the sol is induced by an ice template method to form a layered structure. Freeze drying to remove the solvent, forming a layered frame structure with parallel layered confinement spaces inside the frame, introducing the energetic material solution into the confinement space of the layered frame structure, crystallizing to form energetic material crystals, and constructing energetic material filled Layered frame composite structure. The invention can obtain the composite energetic material with a sandwich stacked layered structure, so as to obviously improve the safety performance of the composite energetic material and effectively improve the comprehensive performance of the composite energetic material.

Description

technical field [0001] The invention belongs to the design and control method of energetic material composite structure, and specifically relates to a composite structure of energetic material filled layered frame and its preparation method. The layered frame structure is prepared by adopting the joint ice template method and the recrystallization of energetic material solution A composite energetic material with a sandwich-like stacked layered structure is obtained. Background technique [0002] The microstructure of energetic materials has an important impact on their macroscopic properties. [0003] At the molecular level, most energetic material molecules with two-dimensional planar configurations, such as triaminotrinitrobenzene (TATB), 2,6-diamino-3,5-dinitropyrazine-1-oxide (LLM-105), hexanitrostilbene (HNS), etc. are generally better than other configurations of energetic materials, such as octokin (HMX), RDX, and hexanitrohexaazaiso Wurtzane (CL-20) and other ring...
