It is evident that strict control over the composition of a filled thermoset system is vital to establishing the chemoviscosity of the system.
This review of current chemorheological techniques and measurement systems for unfilled and filled thermosets highlights some of the progress so far.
The appearance of yield stresses in filled thermosets has not been extensively studied.
Other work by Rydes included very high shear rate rheometry of filled polyesters, extensional rheometry for flow of filled thermosets through restrictions, and novel and on-line viscosity measurements for the production of filled polyesters.
It is envisaged that a standard method for the rheological characterization of filled thermosets will be developed in the future.
A greater understanding of the processing of unfilled and filled thermosets is of vital importance to many industries including integrated chip manufacturers, aerospace technologies, automotive manufacturers, and many other specialized as well as non-specialized applications.
