Ternary blend composites composed of two immiscible organic phases, polyurethane (PU) and polyamide-6 (PA6), and carbon fibers (CFs) as an inorganic filler are studied in terms of mechanical properties and morphology of the composites. The effects of different filler component ratios on its tensile, flexural, and impact strengths are investigated. Using the scanning electron microscopy (SEM), it is found that the addition of carbon fibers and PA6 is beneficial for raising the mechanical strength by increasing the dispersed interface phase. The optimum impact properties of CF/PA6/PU composites were obtained when the PA6 content in the 15 vol.% CF/PU composite was 6 vol.%.
