<P>PROBLEM TO BE SOLVED: To provide a hydrogen tank liner material having excellent gas barrier properties and superior impact resistance even at low temperatures. <P>SOLUTION: The hydrogen tank liner material comprises a polyamide resin composition which comprises (A) a polyamide resin at 85-40 wt%, (B) a copolyamide at 5-30 wt% and (C) an impact resistant material at 10-30 wt% with respect to the total weight of the polyamide resin composition. Preferably, the (B) copolyamide is PA6/66, and the (C) impact resistant material is an acid-modified ethylene/alpha-olefin-based copolymer. <P>COPYRIGHT: (C)2009,JPO&INPIT |
