Abstract
The invention relates to a preparation process of a space type high-heat-explosion energy storage fragment, which is characterized in that the coating of a fluoropolymer material on nano aluminum is more sufficient by a physical modification method on the basis of the fluoropolymer material, and the energy can be released at maximum efficiency. In addition, the high-explosion heat energy storage structural member is three-dimensionally filled on the basis of the active fragments. The energy storage structure is introduced, so that the damage area is greatly increased when the target object is impacted, and the stealth material is greatly damaged. The introduction of the high-heat-explosion material improves the energy release efficiency of the energy storage structural member with the enlarged damage area. The energy storage structural members are three-dimensionally distributed in the broken piece in a double-cone mode, so that the damage angle is more comprehensive, and the damage area is further improved. In summary, a space type high-explosion heat energy storage broken piece plays a very important role in the field of efficient damage.
Description
Technical Field
The invention relates to a preparation process of a space type high-heat-explosion energy storage broken sheet, and belongs to the field of energy-containing materials and active broken sheets.
Background
Fluoropolymer-based active materials are a very important metastable structure. By means of the detonation-like effect, the target is hit, and in addition to kinetic energy penetration, the detonation-like detonation effect also has high-temperature and overpressure effects, so that the target is damaged to a great extent. The energy storage broken piece is a further innovation of the fluoropolymer active material. The energy storage spiral structural member is filled in the broken piece. Under the action of the launching and flying overload forces, the damaged units in the weak constraint state can be subjected to structural damage to release energy storage fragments, and the energy storage fragments have excellent damage effects on thin shell structures such as thin aluminum plates, fiber reinforced resins, aluminum oxide ceramics, glass ceramics, quartz ceramics, ceramic matrix composite materials and the like.
In recent years, a series of fluoropolymer-based active fragments have been developed by research and development teams, beginning at the university of Beijing. The fluoropolymer matrix active material has excellent comprehensive performance and is widely focused by scientific researchers. So far, there have been team initiated studies of energy storage fragmentation. On the basis of single energy storage broken pieces, the damage power of the broken pieces is further enlarged, and the method is a significant subject.
Disclosure of Invention
The invention aims to further improve the damage capability of the current active fragment, and belongs to the field of special damage technology research.
The preparation of the energy storage structural member introduces substances such as ferric oxide, copper oxide and the like on the basis of the original basic formula, so that the energy storage structural member has a larger bursting effect during penetration and destruction. The core-shell type nano aluminum/fluoropolymer energetic material is adopted, and the preparation steps can be generally summarized into surface functionalization, liquid fluororubber coating and a large amount of polytetrafluoroethylene coating. Polytetrafluoroethylene is hardly dissolved at normal temperature and normal pressure, and fluororubber can be dissolved in organic acetone at normal temperature and normal pressure. The method provides a good idea for us, and the polytetrafluoroethylene and the aluminum particle are well mixed and coated through the transition of the fluororubber. And the space type high-explosion-heat energy storage broken piece is obtained through filling, press fitting, sintering and other processes.
Advantageous effects

The nano aluminum/fluorine polymer material with the core-shell structure is obtained by a physical coating method, and the operation is simple and easy to implement.
2. In the formula of the energy storage material, a high-heat explosion synergistic agent with a certain proportion is introduced, so that the damage capability of a single energy storage structural member is improved. The inside of the broken piece is spatially filled in the broken piece in a three-dimensional mode with a double-cone structure, so that the damage effect is greatly improved.
