14—a Casting Technique for the Determination of Bending Strains in Carpet Fibres

An account is given of experiments in which samples of carpet are held under a vertical load while immersed in an acrylic resin of low initial viscosity. After the resin has set, thin sections are cut perpendicular to the carpet backing, which enables measurement to be made of the bending strains in the carpet. Bending strains as high as 0·1 are obtained, and the possible relevance of these values to those arising during normal carpet wear is discussed.
