Fabrication and properties of sphere CL-20/RDX composites with different molar ratios.

Micronsized spherical CL-20/RDX composites with uniform size were prepared by an electrospray method. After preparation, the morphology, crystal structure, thermal decomposition property, explosion performance and mechanical sensitivity were characterized. Different structures existed in the CL-20/RDX composites with different molar ratios. The CR11e composites had the lowest apparent activation energy and the lowest critical temperature of thermal explosion. The explosion pressure and mechanical sensitivity of CL-20/RDX composites were lower than that of raw CL-20 and decreased with increasing RDX content. [ABSTRACT FROM AUTHOR]
