Abstract
A closed-form expression of the interface strength between a fiber and a matrix is obtained using a continuum approach based on van der Waals interactions. The explicit solution of the interface delamination of fiber-reinforced composites with functionally graded interphase under three-dimensional load is derived. The present analytical results indicate that the delamination behavior of the fiber-reinforced composites highly depends upon the interphase thickness, the fiber radius, the Young's moduli and Poisson's ratio of the fiber and the matrix. The present analytical solution provides a sufficient support for the later research on the mechanical behaviors of fiber-reinforced composites and finally for developing new micro-composites.
