Notes:
Determination of the change in electrical dissipation factor and capacitance of epoxy/graphite and polyimide/graphite composites during compression molding provides a reproducible means of obtaining low void content composites by permitting accurate application of low pressure at the resin gel point. Of the two parameters, change in dissipation factor was found to be the more sensitive to molecular changes in the resin matrix as well as to variations in solvent content, particularly with the polyimide systems. The simple laboratory equipment required to carry out these electrical measurements is described.
