Abstract
Two series of 10% polytetrafluoroethylene (PTFE)/polyether ether ketone (PEEK) composites reinforced with potassium titanate whisker (PTW/PTFE/PEEK) and chopped glass fiber (GF/PTFE/PEEK) were prepared and characterized. We investigated the effects of the additives on thermal stability, tribological properties, mechanical properties, and rheological behavior. The results illustrated that the mechanical properties of 10% PTFE/PEEK blend can be dramatically improved by incorporating either PTW or GF; however, the reinforcing effect of GF was found to be superior. It was found that 1% additive resulted in blends with the best tribological properties. Compared to the unmodified blend, the friction coefficient and wear rate of the 1% PTW blend decreased by 7.2% and 21%, respectively, while the corresponding values of 1% GF blend decreased by 0.66% and 51%, respectively.

Abstract
The molecular dynamics of flax-reinforced ethylene–propylene–diene monomer (EPDM) composites, with increasing quantities of flax (EPDM0–EPDM20), was investigated by dynamic mechanical analysis. Multifrequency experiments were also performed in order to distinguish between the relaxation and the kinetic events. Also the time–temperature superposition was applied to the multifrequency results for obtaining the master curves. They were used to anticipate the behavior of the composites in time and to calculate the activation energies using the Williams–Landel–Ferry equation.
