Materials Morph, Meld, and Move Ahead

Today's components are continually being replaced with lighter, tougher and multi-functional ones. In the past, car doors used several metal brackets, supports and clips; now one large plastic plug is being used to combine and replace them. Metal stampings in automobile engine compartments are being replaced, as fluid containers are being molded together [fan shroud, overflow coolant reservoir and washer fluid] to reduce production costs and overall vehicle weight. Metal panels such as car hoods, are being replaced with plastic ones. Kevlar has been examined closely for certain automotive applications. The fact that Ford went on a buying spree of salvage yards (around yr. 2000) in order to reclaim plastic used in autos for recycling and reuse, should be an indicator of future trends. High Strength Low Alloy (HSLA) steel has been introduced in many applications, as well as exotic materials when cost-effectiveness and performance warrants the use. Electrical components are continually being redesigned to be more easily manufactured and cost-effective. One example is the "vanity mirror" - the metal contacts and light bulb clips are stamped as one part, on a continuous roll, then separated when assembled.

I see future trends leading to a significant increase of high-strength plastics in autos, as well as fabric where applicable. Hard shell roofs that can easily be retracted and stored automatically, autos that can be modified to hold either passengers or freight, colors that can be changed quickly and cheaply, are a few directions they may be headed. Insulated (or heated/chilled) compartments that allow for transportation of hot or cold items are LONG OVERDUE in automobile designs. Windshields that darken automatically, or adjust to the driver's preference are likely to become commonplace soon also. More camera use and GPS units are likely to appear. A view from behind the vehicle will likely be projected on the windshield when the reverse gear is activated. Sensors may read what would otherwise be a blind spot when the turn signal is activated - and sound a warning that another vehicle is near. Batteries will be lighter and more powerful, and will be incorporated more and more, as well as incorporation of solar cells into certain vehicle body materials and designs. More interior panels will incorporate passive speaker designs as well. One day, the traditional "Jeep" may be replaced with something of an amphibious nature. Personally, I would like to see a return of the "direct air vent" - there are days I don't want to run the air conditioner, but having the window down makes too much noise and generates too much inside air turbulance.
