Abstract

Weibull theory works well for brittle materials. However, its application to composites is not very clear. The present study is a comparative parametric evaluation of flexural and tensile strength ratios, and fiber bundle stresses of axial composites with brittle fiber bundles. A composite based model that utilizes Weibull’s theory is developed and compared with derived Weibull’s theory for brittle fiber bundles. It was found that the predicted strength ratios and the stresses are of similar magnitude to that of Weibull’s and the model converges to unity for composite materials with little or no variability.
