The door-mounted rear view mirror with a plastic body, now a virtually universal feature, was a French innovation, introduced with the Renault 14 in 1976. The great majority of today s mirror housings are moulded in glass reinforced nylon, in a variety of formulations based on both PA 6 and PA 66. Black UV-stabilized grades are normally used, with body colours an added refinement for high series models (see Fig. 5.20). Reinforced nylon is used because of the mechanical performance requirements of remote-controlled mirrors, especially the creep resistance needed for the mechanisms to survive the touch-up ovens. The precise grade selection depends on whether die-castings are used for any of the structural elements (still the...
