A stochastic micromechanics approach to the theoretical prediction of random variaitions of composite material properties is presented here. The motivation for this work is provided by experimental evidence that random variability has a significant influence on the response of structures composed of composite materials. This paper concentrates on the methodology used to compute the cumulative distribution function (cdf) of a given component of composite stiffness or strength that exhibits stochastic behaviour as a result of random variability of constituent material properties and variables related to composite assembly. This study is part of a larger project to develop a reliability based finite element method, capable of modelling structures made from fibre reinforced composite materials with uncertain material property values.
