THE METHODS OF TESTING COMPOSITES PETN - AL

In the work to develop theoretical foundations of methods of nondestructive testing of the composition of composites on the basis of a transparent matrix PETN and aluminum nanoparticles were started. It is proposed to use the effect of changes in the refractive labile matrix coefficient of partial decomposition. The dependence of the optical properties of the aluminum nanoparticles actual radius of the refractive index of the matrix for the monochromatic radiation fundamental and second harmonic of a neodymium laser were identified. It is shown that light scattering efficiency factor, which determines the reflection coefficient essentially depends on the refractive index of the matrix. The results of work are required for the prognosis stability for nonlinear optical devices based labile matrix including an capsule optical detonator.
