In this study, poly (ether ether ketone) /carbon nanotubes (CNTs) nano composites were fabricated by using multi-walled carbon nanotubes (MWNTs) as the filler. Tensile properties of nano composites at before and after glass transmission temperature were studied. At room temperature, the addition of 15 wt% MWNTs increased the tensile modulus (0.10.3% strain) by 89% and the yield stress by 19%. At after glass transmission temperature (200) , they increased by 163% and 42%, respectively. The experimental results showed that the reinforcement of CNTs are more effective for high temperature than room temperature. DMA results showed an increase in storage modulus with increasing MWNTs loading fraction at both below and above the glass transition temperature Tg (around 145oC). Scanning electron microscope and transmission electron microscope images showed that the MWNTs were well dispersed in the matrix and orientated one direction.
