Description
Summary:The structure of a randomly-formed flake-type wood composite mat is further defined and characterized. A model for the prediction of horizontal mass density distribution in a random flake mat is presented through application of two-dimensional random field theory. This model predicts the small-scale mass density variance and the spatial correlation of flake coverage. The predictions agree well with experimental results and computer simulations. Significance and implications of the model development towards practical manufacturing applications are discussed. In addition, equations for the calculation of general structural properties such as overall mat thickness, between-flake void volume content and maximum potential inter-flake bonded areas are presented.
