Something similar to what these guys are selling in a sticker form: https://egrips.com/ I measured (roughly) the static friction coefficient between their material and a smooth piece of plastic; it's just below 2 and a little over 2 with finger skin. It is not tacky at all. The ultimate goal...

@btrueblood: I think you are referring mostly to "strength" throughout your posts; at least that's how it appears to me. In that case, plain PC is the material of choice and you can't go wrong with it. If I'd lock you in a polycarbonate cage and give you a sledgehammer, you'll still be there a...

That composite of yours is obviously not what I need here but it's very interesting, nevertheless! Is anybody making it yet? On the other hand, are you saying that what I'm looking for is not realistic, as it would definitely need to stay transparent over a relatively wide range of temperatures?

I did a quick search on matweb and it looks like 3-4 GPa is pretty much the most to expect. I was thinking however that maybe I could find some kind of sheets reinforced with fibers of a matching refractive index, with minor effect on clarity. Am I out of luck?

A tiny bit of tint (not cloudy) shouldn't be a problem; after all, we're looking at a sheet just over 1 mm (3/64") thick. As for toughness, put it like this: the LCD and probably the entire device would be destroyed beyond recognition before any plastic would even think about breaking. So...

Hi, I'm looking for a suitable material, composite or layered sheet for replacing an LCD overlay, currently made of glass, with the ultimate goal of significant weight reduction. Normally, a hard coated PMMA sheet would do the job in most applications and the weight would be cut in half...

I came across this company back in '08 and contacted them but my project was put on hold and I didn't follow through. I know that they do provide samples at NRE costs and they'll give you a rough estimate based on a drawing you send. http://www.freeformbattery.com/

Guess what the web address is for secs inc? http://www.secsinc.com/ LOL The three companies that you referenced to are mainly part suppliers but all offer custom engineering services and thus could represent just what I was looking for. Thank you!

Thank you for the suggestion. I wasn't exactly looking to employ a person but rather gather some ideas and then have someone design the mechanism, as a gig. My problem is that I don't know where exactly I should ask. Even if I were to place an ad (although it would apply to a forum post, too)...

Now that you calculated a per day volume, I'm getting the too big to handle anxiety. In fact, another marketing tactic could have better results - overprice it and sell just a fraction of the total number. Also try filing for a patent, a broaaad one since this is probably something very easy to...

Even though it could be considered a niche product, this particular niche is very, very large. Strictly limited to your question, I'd say AT LEAST one million units, over the course of 1-2 years after which the saturation, copycats and the end of the world kick in. The above numbers are...

I'm trying to design a little... something. Because it's very early, I can't tell you exactly what the final product will be (if at all) but it'll be very interesting. The main challenge is the mechanical part, which involves creating a sort of a spring loaded latching switch inside a tiny...
