<P>PROBLEM TO BE SOLVED: To secure mechanical properties equivalent to or more than those of conventional materials, to improve moldability by improving fluidity of a resin composition, and to intend cost down of processing expense by shortening molding cycle time, in molding automotive parts. <P>SOLUTION: This molded article includes a thermoplastic polyester resin and a glass fiber, is obtained by injection-molding a resin composition satisfying the following properties: (1) the melt viscosity is ≤60 Pa s at 260°C temperature and 9,700 sec<SP POS="POST">-1</SP>shear rate; and (2) the crystallization temperature at -25°C/min cooling rate is 185°C or higher. The molded article further satisfies: (3) the flexible strength retention (%) is 85% or more when the molded article is treated for 1,000 hours under conditions of 85°C temperature and 90% relative humidity. <P>COPYRIGHT: (C)2013,JPO&INPIT |
