Dynamic shear rheology

WebJun 2, 2024 · Composite propellants are highly filled polymer suspensions containing 84–90% solids, which makes the rheological behaviour very complicated. The present study deals with the viscoelastic behaviour of a composite suspension consisting of 11–17% aluminium (Al), 0–6% aluminium nanoparticles, 67% ammonium perchlorate (NH 4 ClO … WebRheo-microscopy combines the fields of rheology and microscopy into a unique, powerful tool in which both parts complement the other. It uses a traditional rheometer with a microscope mounted underneath a transparent base plate that allows the user to see visually how samples behave under shear, whilst concurrently collecting rheological data.
