Abstract
Disclosed is a polyamide composite material comprising (A) 100 parts by weight of a polyamide resin and (B) 0.05 to 30 parts by weight of a layered silicate uniformly dispersed in the component (A), wherein the reaction ratio of the components (A) and (B) is 60% or less. Disclosed is also a method for preparing a polyamide composite material comprising making a composite in which a layered silicate, with a cation exchange capacity of 50 to 200 milliequivalents/100 g, is in the swelling condition in a dispersion medium; and mixing the composite with a polyamide resin.
