PURPOSE: A polyamide resin composition is provided to have a light weight and a simple manufacturing process and to have excellent flowability, surface property, antifreeze resistance, and calcium chloride resistance. CONSTITUTION: A polyamide resin composition comprises 75.9-54 wt% of a polyamide resin, 24-45 wt% of a glass fiber, and 0.1-1 wt% of a heat-resistant agent which includes a metal halide-based heat-resistant agent and a hindered amine light stabilizer. The polyamide resin is a polyamide 66. The polyamide resin composition has a tensile strength of 500 kg/cm^2 or more based on ASTM D638 and has a flexural strength of 1,000 kg/cm^2 or more. |
