The mechanical properties of three phase nano-modified carbon fiber reinforced polymeric composites (CFRP) fabricated using Heated Vacuum Assisted Resin Transfer Molding (HVARTM) is investigated. Eight layers of carbon fiber plain weave mats were stacked in quasi isotropic layup and Epoxy 862 resin (non–modified and modified with Boron Nitride Nanoparticles (BNNPs)) was used. For mechanical properties characterization, three ASTM tests were performed. These tests included Tension Test (ASTM D3039), Compression Test (ASTM D6641) and Flexural Bending Test (ASTM D7264). The behavior of control and nano-modified composite laminates were compared. Results indicated that even small percentage of Boron Nitride Nanoparticle can significantly affect mechanical behavior of CFRP as well as progressive failure mechanisms.
