In this study, the fracture strength of hybrid composite epoxy matrix reinforced with woven carbon-basalt fibers were investigated within the framework of Mode I fracture toughness. The present work aimed to determine the strength and toughness properties of hybrid composite influenced by the basalt fiber contents on the carbon fiber reinforced plastics composite (CFRP) based on mode I fracture toughness. A vacuum assisted resin transfer molding technique was conducted to manufacture the composite. Compact tension specimen form with a single-edge notched was subjected to realizing fracture toughness behavior of the interply hybrid composite. Fracture toughness, KIC, of plane-stresses has been calculated from the critical load and crack length based on the two-dimensional analysis according to ASTM D 5045 standard. We used scanning electron microscopy to examine the fracture surface, and micro-fracture of matrix cracking as well as the fiber breakage of interply carbon/basalt/epoxy hybrid composite. The result showed that the toughness of hybrid composite with increasing basalt fiber contents also increased, as shown by the decrease of the crack propagation of the notch. De-bonding and fiber pull-out have dominated the failure behavior of the hybrid composites. Generally, basalt fabric shows potential to improve toughness of a brittle composite material due to its deformability.
