Abstract
Theoretical and experimental results for the magnitude and distribution of interfiber stresses in a transversely loaded composite consisting of an elastic matrix reinforced with elastic fibers are presented. Interfiber stress distribution is also given for an in plane shear load condition. The mathematical model consists of uniformly spaced circular fibers in a square array. An approximate solution is obtained for the interfiber stresses. Theoretical results are compared with results of a photoelasticity investigation, Fil'shtinskii's rigorous elasticity solution for a plate containing rigid circular inclusions, and with results of a rigorous elasticity solution for a three-dimensional problem. The present approximate solution provides good agreement with the experimental results and with the theoretical results obtained by other authors. The method of solution presented can be used for predicting interfiber stresses in composites with various shape fibers arranged in arbitrary arrays, as well as for investigating interfiber thermal stresses, elasto-plastic deformations, and residual stresses.
