In the given work presents results investigation influence interphase interaction on module Young’s of compositionson on the base of unpolar polymer polyethylene of high density (PEHD) polar polymer poliviniliydenftorid (PVDF) and piezoceramic with rombohedrial structure PCR3M, tetragonal structure PCR8 before and after electrothermopolyarization. It has been shown the difference observed between experimental and theoretical values of modulus of elasticity E of compositions is connected, to our mind with not taking into consideration the interphase interactions thickness of the boundary layer and electron-ions processes in compositions systems of polymer piezoceramics.
