Abstract:

The present research investigates experimentally the various wave properties of a particulate composite, simulating a solid rocket propellant. The material used in the experiment is made of a soft polybutadiene as matrix and a filling material in the form of fine aluminum particles. The emphasis is placed upon the dispersion and scattering effects of the filling particles. Since the sizes of the particles range from 10 micrometers to 40 micrometers, the input wave lengths are required to be comparable to these dimensions.
