ESTABLISHMENT OF THE POTENTIAL OF FLAKE REINFORCED COMPOSITES AS ENGINEERING STRUCTURAL MATERIALS

Abstract

The stress-strain behavior of highly idealized model flake composites, composed of disc shaped flake of uniform size and mechanical properties, was considered. An analysis of such a composite under a uniaxial tensile stress was performed, considering the reinforcing elements to act independent of their nearest neighbors. This analysis was then modified to consider interactions between adjacent flakes. For the case where the flakes act independently of one another, the results show that the upper limit of strength available is only approximately 48% of the inherent strength of the reinforcement. A consideration of flake interaction reveals that a larger fraction of the reinforcement strength can be developed under load. techniques for making disc shaped glas flake are given and the limitations of the methods are discussed. Methods for improving the reinforcement efficiency of the flake by altering the geometrical shape from a simple disc to a lenticular form are also considered. (Author)
