活性材料能量释放特性实验评估方法
An Experimental Evaluation Method of Energy Release Characteristics of Reactive Materials
摘要
Abstract
To evaluate and characterize the energy release characteristics of reactive materials under impact,a dynamic energy release characteristic testing device was improved based on Vented Chamber Calorimetry(VCC)test method.The function relations of dynamic energy of reactive materials,quasi-static pressure and reaction efficiency were established.At the same time,aiming at three typical reactive material samples,the verification was performed.The quasi-static pressure inside the chamber after impact response and fireball change process of reactive materials were acquired by a pressure sensor and a high-speed camera.The specific chemical energy released by reactive materials and reaction efficiency were calculated based on the value of maximum quasi-static pressure.The results show that the consistency of specific chemical energy and reaction efficiency obtained under the same formulation and experimental condition is good,which demonstrates the reliability of this method.关键词
