An investigation of the flow, mechanical, tribological properties, such as tensile, bending, impact strengths, friction and wear rate was conducted for various blends of three polymers, namely, LCP (liquid crystalline polymer), PAR (polyarylate) and PA (polyamide). The results were summarized as follows ;
1) The tensile and bending strength of blends of LCP 25/75 PAR(LCP 25%, PAR 75%) was greater than that of neat PAR.
2) The frictional coefficient and wear rate of blends of LCP 25/75 PAR and LCP 25/75 PA were smaller than that of neat LCP, neat PAR and neat PA.
3) The dependence of frictional speed on the frictional coefficient and wear rate of blends approached to that of neat LCP with increasing of LCP content.
