When the wing goes through the air at too great an angle, the airflow around the wing becomes disrupted and the wing no longer produces sufficient lift. As the others hinted, this maximum angle is called the critical angle of attack. A stall has more to do with the angle between the flight path and the aircraft's attitude than with the speed of the air, as an airfoil can stall at any speed if the Critical Angle of Attack is exceeded.
