W. Gossclink, having varying amaunt3 of "air gaps" between thf facing and core, as determined at various points on the sheets by nosouring facing gaugo and over-all gauge after combining. Then points wore sleeted having particular amounts of gap or compression, and tested comparatively for re laxation, seal, end load-deflections. The six points tested, in order frem nest conpressed to least compressed, are a3 follows s Approximately .0015" compression - Sample B No compression and no gap Approximately .0005" gap Approximately .d)0l5" gap Approximately .0025" gap Approximately' .0030" gap Ssmplo A Sample S Sample C Sample D Sample !' 11.0 data appear ca tho attached shoot. Also attached are ioad-doflectic.i graphs. r It was found that all aiffereucos between camples ucro very rrlnor, and can to attributed to normal experimental variation. It is coneludsd that the y.resoncq or absoxco cf air gap3 nakos no significant dli'icrcnco in ths physical propsrtioo tostod. ------------------ " ' Materials Development Laboratory Oj ^/{\ ), 'ch [ r / ,y J.
