摘要
综述了含能材料中TNT为基熔铸炸药(MeltCastExplosives)在增韧增弹上的实验研究,介绍了可用于熔铸炸药增韧增弹的新途径,以及熔铸炸药组分间作用的相关理论研究。熔铸炸药长期以来存在的感度高、脆性易裂等问题限制了其在高性能武器系统中的应用。目前,国内外关于熔铸炸药增韧增弹的研究较少,早期的文献大都针对熔铸炸药的改性研究。因此,解决现今熔铸炸药的问题,实现对其增韧增弹具有重要的科学意义和应用前景。文献表明:(1)国内外在"熔铸炸药增韧增弹"概念上未进行系统总结,也未见任何文献中提出;熔铸炸药改性剂(聚酯纤维、聚氨酯弹性体、HNS晶形控制剂)的研究主要针对的是熔铸炸药的渗油、降感研究,尚未解决熔铸炸药脆性、易裂的根本问题;(2)其它复合材料的增韧增弹技术对熔铸炸药有所借鉴,尤其是纳米粒子以及高分子材料的增韧增弹技术;(3)通过设计和制备与熔铸炸药相容的增韧增弹剂,再将其与熔铸炸药进行物理共混或颗粒级配等技术完成浇铸后进行力学性能、微观性能研究等,可以初步建立熔铸炸药增韧增弹的模型并总结出有关增韧增弹的机理。
A systematic overview of TNT based melt cast explosives in toughening and elasticizing experiments is given. New toughening and elasticizing route, and computational research on interaction of components in melt cast explosives are introduced. Brittleness and cracks in melt cast explosives restrain the application in high performance weapon systems. The research on toughening and elasticizing melt cast explosives can be divided into three explanation： （i） the conception of “Toughening and Elasticizing” is not reported, research on the melt-cast explosives modifier mainly aims at oil saturation and insensitivity reduction, the problem of brittleness and cracks are not solved yet. （ii） toughening techniques of other composites could be used for reference to melt cast explosives, especially toughening and elasticizing techniques of nano particles and polymer materials; （iii） designing and preparing the modifier comparable to melt cast explosives, researching the mechanical properties after blending and casting, start to establish the model and mechanism of toughening and elasticizing melt-cast explosives.
