Importance of Boundary Friction in Measuring Bulk Compression of Loose Wool FibersUniversity of New South Wales, Kensington, N.S. W., Australia
University of New South Wales, Kensington, N.S. W., Australia The conventional method of conducting compression tests on fibrous masses employs a "piston-in-cylinder" arrangement. In its most common form this system overestimates the energy required to compress the fibers since it includes the energy expended in overcoming friction between the fibers and the cylinder wall. A new apparatus is described which both avoids this problem and enables the size of such errors in the conventional system to be estimated. Experiments comparing the conventional apparatus with several versions of the new design are described and some optimum dimensions are established for the latter.
