Abstract. The results of numerical experiments on modeling of shock wave loading of mixtures are obtained by using thermodynamic equilibrium model TEC (thermodynamic equilibrium components) are presented. The thermodynamic parameters are modeled for the mixtures that include epoxy resin as a component. The model allows taking into account the phase transition under shock wave loading, when the substance in the region of phase transition is considered as mixture of low-pressure phase and high-pressure phase. Interest in the investigation of compressibility of such mixtures is associated as with the possibility of creating materials that have the required properties and the properties of the materials themselves. The good agreement of these model calculations with the data of different authors that defined on the experiments basis is obtained. The model allows to describe dynamic loading of solid and porous mixtures comprising epoxy resin and various components such as quartz SiO2, periclase MgO, corundum Al2O3, spinel MgAl2O4, enstatite Mg2[Si2O6]. IntroductionThe investigations of thermodynamics parameters of porous materials including, in particular, the solid organic substances under shock-wave loading are of interest in many problems of modern science; in this regard new models appear for the description of the behavior of such materials, for example [1][2][3][4][5][6][7][8]. These investigations are important in solving the applied problems of dynamic compaction, shock-wave synthesis, and other explosive technologies.Interest in the study of compressibility of mixtures comprising as component epoxy resin due to their properties [9,10]. The composite materials combining the properties of the components are created on base on these mixtures. Epoxy resins are characterized by high resistance to the action of halogens, some acids, alkalis; they also have high adhesion to metals. Additional properties of the composite materials are obtained by using various additives to the mixture. For example, quartz SiO 2 is widely used in optical and electronic devices, in the manufacture of silica refractories and quartz glass. An additional important property of quartz is the existence of polymorphic phase transition under shock wave impact. Substantial change in the volume of such components included in the mixtures allows expanding the range of changes of thermodynamic parameters of the mixtures under shock wave loading. Periclase MgO is important component of magnesite and dolomite refractory. Abrasive materials are produce from corundum Al 2 O 3 . Spinel MgAl 2 O 4 is rare mineral of cubic crystal structure. It is a mixed oxide of magnesium and aluminum (volumetric fraction MgO 28.2%; Al 2 O 3 71.8%). The name of mineral enstatite Mg 2 [Si 2 O 6 ] is derived from the Greek words ενστ ατ ης (enstates) "the enemy", "the resistance",

SYNOPSISHydroxypropyl cellulose (HPC) of degree of substitution three and average molecular weight of 100,000 was processed in a magnetic field of 1.2 T. Films of HPC were cast from water, methanol, ethyl methyl ketone, and 1,1,2,2-tetrachloroethane solutions in a magnetic field using static and dynamic casting techniques. The processed films were evaluated for tensile strength, elastic modulus, microhardness, and molecular chain alignment by wide angle xray diffraction and polarized infrared. The best alignment and hence the greatest improvement in properties was obtained using a combined magnetic field and flow alignment procedure. These samples showed no increase in the elastic modulus, a 106% increase in the tensile strength, a 21% increase in the microhardness, and were dichroic. 0 1994
