Hybridizing low strain (LS) to failure fibers with high strain (HS) to failure fibers is one of the most commonly used methods for achieving pseudo-ductility. Fiber hybridization can be performed using various methods, such as interlayer or layer-by-layer, intralayer or yarn-by-yarn, and intra-yarn or fiber-by-fiber. In hybrid composites with different failure strain values, achieving an appropriate fiber volume fraction (Vf) for the two different fibers is critical for producing progressive failure of the composite. Recent studies have indicated that a thin-ply interlayer unidirectional (UD) hybrid architecture is a promising approach for achieving favorable ductile or pseudo-ductile behavior in composites. In most cases, such UD interlayer hybrid composites are produced by embedding thin carbon fiber (LS) layers between glass fiber (HS) layers to create pseudo-ductility through the progressive fragmentation of the carbon layer and delamination of the carbon/glass interface.
