The present disclosure relates to a polyamide-based polymer composition with superior fluidity and a polyamide-based composite material with superior mechanical strength prepared therefrom. More specifically, it relates to a polyamide-based polymer composition containing 0.1-5 parts by weight of dicyclohexylmethane bisdecanoamide, which is a cyclic compound, as a fluidity control agent based on 100 parts by weight of a mixture consisting of 20-90 wt % of a polyamide-based resin and 10-80 wt % of a reinforcing fiber, a polyamide-based composite material prepared using the same, and a method for preparing the same. The polymer composition according to the present disclosure, wherein dicyclohexylmethane bisdecanoamide is used as a fluidity control agent, provides an effect of reducing friction between a molten resin and a processing machine and greatly reducing torque by effectively dispersing a reinforcing fiber in a polyamide-based resin. Also, the polymer composition according to the present disclosure may be usefully used in compounding, extrusion molding and injection molding of polyamide-based engineering plastics containing reinforcing fibers at high contents. In addition, according to the present disclosure, the addition of the fluidity control agent greatly improves flowability during processing. Therefore, a polyamide-based composite material with superior mechanical strength can be prepared under relatively mild conditions because uniform mixing of the reinforcing fiber and the polymer resin is induced.
