ABSTRACT In certain application of fiber reinforced polymer composites fracture resistance is required. The aim of this study was to improve the interfacial adhesion between plain woven carbon fiber (CF) and epoxy matrix filled with 0.3% of nano-cellulose (microfibrillated cellulose-MFC) modified with liquid rubber (carboxyl-terminated butadiene acrylonitrile-CTBN) with different contents. CF/Epoxy/MFC/CTBN composite was characterized by different techniques, namely tensile, fracture toughness (mode I) test and scanning electron microscope (SEM). The results reveal that at a fibre content 0.3% of MFC and 1%CTBN, initiation and propagation interlaminar fracture toughness in mode I improved significantly by 39% and 57% respectively which could be attribute to strong adhesion between filled epoxy, carbon fibre and rubber. This can be explained by SEM at given weight as well; SEM images showed that in front of the tip, fiber breakage during initiation delimination as well as the extensive matrix deformation between fibers accounting for increase fracture toughness.
