It is evident that strict control over the composition of a filled thermoset system is vital to establishing the chemoviscosity of the system.
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.
The filler effects on the chemoviscosity of thermosetting resins has not been studied extensively, but is vital to understanding the rheology of filled thermosets.
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.
The appearance of yield stresses in filled thermosets has not been extensively studied.
