Statistical Geometry of a Fibrous Network

The statistical geometry of fibrous networks is described in terms of the fibre and sheet dimensions and geometric probability. The method has been developed for random two-dimensional structures and extended to cover deviations from randomness (orientation and flocculation). It is also applied to a multi-planar structure as a first approximation to three-dimensional structures. Further approximations to three-dimensional networks are discussed. Experimental results for two-dimensional structures are presented.
