[0076] Examples 1-4 and Comparative Examples 1-4: Preparation of Polyamide Clay Composite Composition

[0077] In an exemplary embodiment, the polyamide clay composite composition according to Examples 1-4 and Comparative Examples 1-4 is preferably prepared by properly mixing the above-mentioned constituent components in the mixing ratio shown in Table 1 below:

[0078] [Table 1]

[0079]

[0080] [Preparation of samples for performance measurement]

[0081] Preferably, the polyamide clay composite compositions according to Examples 1-4 and Comparative Examples 1-4 were suitably melt-extruded in a twin-screw melt extruder heated to 250° C., and formed into pellets.

[0082] In a further preferred embodiment, the pellets thus formed are dried at 100° C. for 4 hours and ASTM samples are suitably prepared using the dried pellets in a screw-type syringe heated to 250° C. to determine, for example, the flexural strength The mechanical properties of , tensile strength and imp...
