Abstract: Sintered polytetrafluoroethylene is non destructively degraded so as to be grindable to a powder of an average size of less than 10 microns by a combination of irradiation by electrons or other subatomic particles in the presence of oxygen or air and concurrent or subsequent heating at temperatures below the melting point of the material. The referred effective and economic range of irradiation, heat and time at temperature is approximately 50-150 Mrads, 150°F to 600°F for at least about one-half hour depending upon desired average particle size and melt flow characteristics and acceptable yields of fine powders.

Abstract: A method of making a bond structure and a bond structure are provided that produce concurrently a peel bond and a lap bond. One end (2) of a sheet (1) to be joined to a second end (7) of the same or other sheet (6) is folded back on itself (3, 4) and one end (7) et the other member (6) inserted. The two pairs of contacting surfaces thus! formed are subsequently bonded to each other. The bonding may be by any means and the clamping force across the bond during bonding need be applied from one side of the sheet only. By insuring that the peel bond fails before the material (fig. 2), a flat lap bond (fig. 3) may be achieved by causing only the peel bond to fail.
