Research Progresses and Prospects of Compression Molding of High-performance PBX
Pressed PBX was widely used in modern high-efficiency damage weapon warheads due to their excellent detonation and mechanics properties.The continuous changes in the future combat environment and strategic requirements were driving the development of pressed PBX towards high quality,high safety,and efficient molding and manufacturing.Thus,the current research status and problems facing the pressed PBX in molding quality and performance control,compression molding safety,and automatic manufacture were summarized herein.Firstly,the research progresses in the control of forming quality and performance of PBX was explored,including the evolution law and den-sity inhomogeneity of explosive particle densification,damage evolution mechanism and interface per-formance control,residual stress detection and control.Furthermore,the compression molding safety of PBX and the current research status in digital and automatic manufacture were analyzed and dis-cussed.Finally,based on the analysis of the current research progresses,the future development trends and challenges in the field of PBX compression molding were prospected.
