Windscreen manufacture for project car 1

[wrightti]

Hi,

Im looking for some information regarding windscreen manufacture. This is for a 1-off road vehicle (which is basically just my own project for now)

Ive also posted this question in the aeronautics forum, so I hope its ok to duplicate here.

An idea of the geometry I'm hoping to achieve is attached. Its largely a single curve at this stage to simplify manufacture.

Being a one off and for a personal project, expensive high pressure moulding techniques are out of the question. Obviously some sort of moulding will be required, and this is within my capability, though I imagine the surface finish requirements on any tooling would be very high.

Finally, Id like some advice on how to manage visual distortion. Is there some geometry (high curvature sections?) which will cause problems?

cheers guys

Tim

If using a plastic a thin film may be an easy way to replace any wear or scratches.
I have ridden in a car with a plastic windscreen and besides vision distortion the direct sun diffused and blinded us for a while. Although that was some time ago I am sure the new acrylics are much better.

I don't know anything but the people that do.

In response to the OP, here's a good technical reference on scratch resistance of plastic windscreen materials:

You can check into Exatec too, I spoke with them a few years ago bout making some coated plexi for a street car.
