The fracture toughness and failure behavior of interlaminated hybrid composites were investigated. Hybrid interlaminated carbon and basalt fibers have been manufactured by fluid injection molding. The compact tension (CT) from hybrid composite panel has been used for Mode-I tension tests based on ASTM-D5045 standards. The experiment was aimed at investigating the stress intensity factor (KIC ) of interlaminated hybrid composites having different stacking of carbon and basalt fibers. The experimental results showed that hybrid composites with configuration CBCBC (B2 code) have maximum average values about 5.8% and 2.0% higher than the C4 and B1 configurations, respectively. Replacing 20%, 30%, and 40% carbon by basalt fibers led to decrease in stress intensity factors (KIC ) by 8.87%, 7:56%, and 5.46%, respectively. Additionally, SEM measurements showed that the dominant failures that occurred include delamination, pull-out fiber to epoxy and fiber splitting. Thus, the fracture toughness of composites is significantly influenced by interlaminated hybrid composite epoxies.
