Abstract

The stresses induced in and around a coated short-fiber composite are investigated by use of the Boussinesq-Sadowsky stress function. The coated fiber is assumed to consist of two confocal spheroids and it is embedded in an infinite body. The major parameters in this analysis are the fiber aspect ratio, the coating thickness-to-fiber radius ratio, the coating-to-matrix stiffness ratio and the fiber-to-matrix stiffness ratio. It is found in the analysis that the stiffness and thickness of the coating and the fiber aspect ratio have some effect on the stress field in and around the coating in a coated short-fiber composite.
