Hybridisation is one of the approaches to introduce pseudo-ductility to brittle composite materials. In this approach, two layers with different types of fibre are combined and a new stress-strain response which depends on the material properties of the components and thickness of the constituents is produced. In this paper, an analytical method of predicting the damage progress of UD hybrids is proposed which has an acceptable accuracy and is significantly faster than numerical methods such as FE. A new chart called a "damage mode map" is produced that relates the configuration of a UD hybrid to its predicted damage scenario straightaway. This map has been found to be a very useful tool to find the optimum configuration in designing new hybrid composites.
