| Résumé : |
An innovative manufacturing of unidirectional nano-phased carbon fiber laminates doped with b-SiC nanoparticles was developed using the combination of filament winding and online solution impregnation method. The technique was developed to prepare nano-phased carbon prepreg used in the fabrication of the nano-phased laminates were successfully manufactured. The sample coupons were characterized by TGA (Thermo-gravimetric analysis), DSC (Differential scanning calorimetry) and SEM (Scanning electron microscope). TGA results showed that the nano-phased laminates were thermally more stable (about 7°C) than the neat counter parts. DSC results indicate the maximum cross-linking of the polymer chain in the presence of SiC nanoparticles. SEM micrographs show that the carbon fiber used are ~10 micrometers in diameter and the nanophased resin is uniformly wetted all over the fiber volume. Flexure test results revealed significant improvement of 32% in flexural strength and 20% in modulus when compared to the neat system. |
