The cohesive law of particle/binder interfaces in solid propellants
School of Engineering, University of Aberdeen Fraser Noble Building, King's College, Aberdeen AB24 3UE, U.K.
Solid propellants are treated as composites with high volume fraction of particles embedded in the polymeric binder. A micromechanics model is developed to establish the link between the microscopic behavior of particle/binder interfaces and the macroscopic constitutive information. This model is then used to determine the tension/shearing coupled interface cohesive law of a redesigned solid rocket motor propellant, based on the experimental data of the stress-strain and dilatation-strain curves for the material under slow rate uniaxial tension.
