Abstract
Composite materials have a large number of parameters associated with their manufacturing. It is not physically possible to control all these parameters, and hence variation in the material properties result. In this paper, for a better modeling of the material properties, these are treated as random variables. Static response characteristics of graphite/epoxy composite laminates are obtained with the help of Monte Carlo simulation and the Finite Element Method (FEM) for different boundary conditions, thickness ratio, aspect ratios and fiber orientations. The input material property mean and variance are assumed to be known. From the limited analytical study conducted it is observed that a single design curve can predict normalized characteristics for all the parameters considered.
