US 8,044,139 B2 · Fiber reinforced nylon composition

Abstract

The present invention relates to a fiber reinforced nylon composition, wherein the composition includes (A) 25 to 75 parts by weight of a polyarylamide resin, (B) 25 to 75 parts by weight of a reinforcing fiber having a cross-sectional aspect ratio of 1.5 or more, and (C) an impact modifier, and the impact modifier is included in an amount of 1 to 10 parts by weight based on 100 parts by weight of a mixture of the polyarylamide resin and the reinforced fiber. According to the present invention, the fiber reinforced nylonresin composition may exhibit minimal or no warpage, can have excellent fluidity and impact resistance, and can provide high whiteness and a glossy-coating due to minimal or no surface change after dipping in boiling water.
