METHOD OF DETERMINING ADHESION OF FILLER PARTICLES TO POLYMER BINDER

摘要

FIELD: physics. ^ SUBSTANCE: method of determining adhesion of filler particles to a polymer binder involves loading a sample with a tensile load and recording the time at which the bond between the particles and the binder breaks. The sample undergoes volumetric tensile loading in an immersion liquid placed in a cylinder with a piston together with the sample. The moment the adhesion bonds in the sample break is recorded based on the change in the linear relationship between the tensile load on the piston and deformation. ^ EFFECT: method which enables to simulate the state of loading material in wall layers even in case of visible integrity of the sample with different types and shapes of filler particles. ^ 4 dwg
