Abstract

The mechanical and thermal properties of Benzoxazine epoxy system containing multiwalled carbon nanotubes (MWCNTs) are studied. The CNTs bring about significant improvements in flexural strength and modulus. The thermo-mechanical properties are characterized using the dynamic mechanical analysis (DMA), thermo-gravimetric analysis (TGA) and thermo-mechanical analysis (TMA). The results show that the storage modulus and glass transition temperature increase with increasing CNT content. The addition of CNTs has an ameliorating effect of lowering the coefficient of thermal expansion in both the regions below and above glass transition temperature. This observation has a particular implication on using the Benzoxazine epoxy nanocomposites requiring low shrinkage and accurate dimensional control. The mechanical and thermal properties of CNT-Benzoxazine nanocomposites are compared with those of typical epoxy nanocomposites containing similar CNTs.
