Title Of Article :
Mechanical and Termal Characterization of Woven Carbon Fiber Reinforced Carbon Nanotube-Epoxy Composites
Abstract :
The scope of this study was fabrication and characterization of woven carbon fiber reinforced composite with multi-walled carbon nano-tubes modified epoxy matrix. For this purpose, modified epoxy matrix with multi-walled carbon nano-tubes at a concentration of 0.3 wt % and twill 4/4 woven carbon fiber fabric as textile reinforcement were used for fabricating nanomodified composite plates. The effect of multi-walled carbon nano-tube fillers on epoxy matrix system and carbon fiber reinforced composites were also studied. In this study, the tensile tests were performed in both the warp and weft direction, in-plane shear and three-point bending tests were also performed to characterize the mechanical performance of the composites. In addition, differential thermal gravimetry (TG-DTG) and differential scanning calorimetry (DSC) analysis were performed by using the simultaneous thermal analysis unit (TG-DTG/TG-DSC/TGA) to investigate the effect of multi-walled carbon nano-tubes. Furthermore, the microstructure of the multiscale carbon fiber reinforced composite was investigated by scanning electron microscope (SEM) and optic microscope after tensile tests. Tensile, flexure, TG-DTG and DSC analysis confirmed that matrix modification could improve the mechanical properties and thermal stability of the composites compared to neat resin. In addition, SEM and optic microscope images taken from crack propagation surfaces also supported the improvement of composite material performance.
