AB  - In this study, a two-scale 3D model for the tensile behavior of unidirectional hybrid composites is proposed. In the fiber scale, the tows are defined as fiber/matrix system. In the tow scale, hybrid composites are regarded as combination of two (or more) types of tows. The strength estimation of fibers is statistically described by the two-parameter Weibull distribution. In both scales, analyses are based on shear slag model and taking the fiber/resin interfacial toughness into account. The proposed model is then used in simulation the tensile behavior of hybrid unidirectional composite bars reinforced by fibers of carbon and glass. Numerical simulations agree well with experiment results. Relations among the carbon fiber volume fraction and the stiffness, strength and tensile toughness are obtained.
