Hybrid composites composed of carbon and sisal fibers are gaining prominence due to their ability to balance mechanical performance with sustainability. These materials are particularly promising in structural applications where fracture resistance is a critical design factor. Fracture toughness, which reflects a material’s ability to resist crack propagation, is influenced by the fiber-matrix interface, fiber hybridization strategy, and microstructural parameters. This study presents a review of current methods for characterizing fracture toughness in hybrid composites and explores modelling techniques that predict fracture behavior. Emphasis is placed on the interaction between synthetic (carbon) and natural (sisal) fibers, including how their contrasting properties influence crack deflection, fiber pull-out, and energy absorption mechanisms [1]. Modelling approaches such as finite element analysis and cohesive zone modelling are also discussed, offering insights into the prediction of fracture response under different loading conditions [2]. This work provides a framework for optimizing hybrid fiber composites in applications requiring high fracture resistance with environmental considerations [3].
