Problem Statement

The vibrating needle curemeter is a commercial device which continuously monitors material cure right through from the liquid to the solid phase in liquid curing systems for rubbers, plastics, paints and resins. It provides a continuous record of the development of viscosity and stiffness. The amplitude attenuation of a vibrating needle at resonance frequencies is the basic mechanism whereby the monitoring of the progress of a given cure is achieved. The Study Group was asked to develop a clearer understanding of the underlying success of the curemeter and via that understanding to assess the prospects of further utilization of the curemeter in evaluating rheological properties of a given cure.
