Thanks for the invite. Interesting site.\n\nRe: technology - Don't rely on any tool you don't know how to make.

This project will take 3 years to complete./ The web site is not complete yet so only some of the links work\nListed below is the web site

Check this site i think its the best site for engineers

Dupont is a global leader in polymers.  They are a good place to start, and their website can refer you to their distributors.

I'll go out on a limb and suppose that you need some very simple projects that can demonstrate polymer properties to the layperson.\n\nPhysics:  \n\nIf you take a rubber band, an elastomer, suspend a weight from it, and gently heat the rubber band with something like a hair drier, you can demonstrate that polymer chains prefer to adopt a random coil configuration rather than a straight, linear configuration. (I'll leave out the basic thermodynamic details so you can delve deeper into the subject.)\n\n\nChemistry:\n\nTo demonstrate the differences in size between polymers and small molecules, look up the size of a single water molecule and then get a piece of foam rubber.  The water molecule's size is on the order of Angstroms, while the foam rubber is essentially one gigantic molecule.\n\nIf you have access to sebacoyl chloride and hexamethylene diamine, you can make Nylon-6 by using equal parts of both reactants.  The polymer forms at the interface of the two liquids, and you can use tweezers to pull the polymer out of the reaction vessel.  NOTE:  Proper safety precautions MUST be followed as both chemicals are irritants. \n\nI've left out sources and a lot of other details so you can research the physics/chemistry of the examples given here.

Sourceforge is a good resource for public projects like this, although you typically need to have something to start with.\n\nAlso, I have a random idea...why don't you start a website for posting new ideas online?

Good luck by Fri. Don't forget to site sources ;)

Here's something I pulled up from the company website.  http://www.lehighcement.com/AboutLehigh/AboutLehigh-History.htm

You're best bet is to contact the resin manufacturers.  When you get the operator just tell them you have a technical question regarding (whatever you want) and they'll transfer you immediately....for some reason most people wig out when they hear the word "technical."  Try Geon, Solvay, Vinnolit, Vinycel, Kaneka, Mitsubishi, or Formosa to name a few.  You might also have luck with PVC compounders such as PolyOne or Marchem.  Otherwise, you could by some books devoted to the subject - The Encyclopedia of PVC Vols 1-4 is an excellent resource.  However, unless you have a few hundred bucks at your disposal I don't reccomend this.  Good luck!

Keep checking online. I did print out plans with sources of material last year.  Also, there are finished frames for sale. Maybe Instructables? There are projects for welding bikes,
