The objectives of the Navys CL-20 Manufacturing Technology project are to develop and implement advanced process technology that will improve the reproducibility and quality of CL-20, improve CL-20 sensitivity, and reduce the cost of CL-20. One subtask in this project was the identification of key factors and properties that influence the sensitivity of CL-20. A series of round robin tests was conducted where impact and friction sensitivity testing were run on 14 samples of CL-20. These samples were prepared using various synthesis andor recrystallization techniques and having various impurity levels. Samples were supplied by the U.S. commercial supplier, ATK Thiokol Propulsion Company, the Navy Naval Surface Warfare Center, Indian Head Division, and Naval Air Warfare Center Weapons Division, China Lake, and the Army TACOM-ARDEC as well as Aerojet and suppliers from outside the United States Nexplo-Bofors and SNPE. Round robin results indicate that CL-20 sensitivity is largely unaffected by CL-20 preparation method, purity, and particle characteristics.
