Abstract : Samples were processed by Hi-Tech Ceramics and then supplied to Alfred University for firing, electroding and testing. Previously supplied samples encompassed: four pore sizes (15,30,45 and 65 ppi), undistorted and 2:1 aspect ratio distorted foam, two densities (10 and 15%), face coated and non-face coated reticulate. The samples supplied during the current reporting period included the same four pore sizes but of an increased, 3:1 aspect ratio, degree of distortion. Web coating of the 3:1 foam was more difficult since the greater distortion results in a more dense structure to impregnate and coat with slurry. The 15 ppi, 3:1 distorted foam processed to approximately 15% density gave webs of good integrity and resulted in an increase in dh over the 2:1 distorted foams. Over forty samples of this pore size and distortion have been supplied to Alfred University for evaluating alternate epoxy materials and electrodes for the 3-3 composites. jg p.2
