Peculiarities of structural variations at crystallization of highly filled composites on polymeric basis

Composite samples with polymer matrixes of different compositions are investigated. The volume fraction carbon fillings of globular form quasi-isotropically distributed in the samples was found to range from 0.4 to 0.7. Under increasing the density, the modulus of elasticity and strength of the comp...

Description
Summary:	Composite samples with polymer matrixes of different compositions are investigated. The volume fraction carbon fillings of globular form quasi-isotropically distributed in the samples was found to range from 0.4 to 0.7. Under increasing the density, the modulus of elasticity and strength of the composites under discussion, some the quasi-periodical oscillations of mechanical parameters are discovered accompanied by changing both the value and sign of the Poisson coefficient. The nature of this phenomena has been established and a model of the structural variations has been proposed.
