The separation of layers in laminated composites called delamination is the main mode of failure under transverse and shear loadings. Interlaminar fracture toughness is a material property that describes resistance to delamination. Increasing the interlaminar fracture toughness is one of the main motivations in the laminated composite field. In this regard, chopped glass fibers were interleaved between the layers of laminated composites to improve the interlaminar fracture toughness. The chopped glass fibers were processed to take the form of a tissue, which is a thin nonwoven mat material composed of randomly-oriented short glass fibers. This tissue is then placed between the layers. The vacuum infusion method was used for the manufacturing of composite samples. To measure the Mode-I and Mode-II interlaminar fracture toughness of the composite, a double cantilever beam (DCB) test, and an edge notch flexure (ENF) test was conducted, respectively. The addition of chopped glass fibers has enhanced the Mode I and Mode II fracture toughness by 64% and 27%, respectively. The influence of the chopped glass fiber on the crack path or fracture surface was investigated using scanning electron microscopy (SEM).
