Hybrid composites reinforced by two types of fibres e.g., carbon and glass have been widely researched. These two types of fibres are distinct in density and cost. An optimisation study on the carbon and glass fibre reinforced hybrid composite in three-point bending is presented in this paper. Both unidirectional and multi-directional hybrid composites are studied. The objectives are minimising the cost and weight with the flexural strength being the constraint. The three-point bending is simulated by a Finite Element Analysis based model, and optimisation is done with non-dominated sorting GA-II (NSGA-II). This optimisation approach can be extended to hybrid composites reinforced by other types of fibres.
