Reverse engineering for rubber tyre
Reverse engineering for rubber tyre
(OP)
I want to make some toy car tyre. And I have no idea what are the material needs to be mix. So, I am planning to send some rubber tyre to a lab for analysis. According to the lab, they said they can get close to 95% of the material contains in the tyre. And they will let me know how the materials react into the rubber. So that I can fine tune the end product. It sounds too good to me. I think it should not be so easy to do the reverse engineering. So, I have some questions:
1. Analysis then use the same contents to mold the tyre. You think it works?
2. How close I can get to the lowest.
3. Is there any treatment of material? Ex, dry age for a steak. Do I need to dry age for a material.
4. Is there any company/person that can help me to get success?
thanks

RE: Reverse engineering for rubber tyre
For the high end tyres you could use norsorex http://www.astrotech.at/index.php/griptyre.html, otherwise natural rubber is a good option.
The design of the thread is very important too.
RE: Reverse engineering for rubber tyre
Natural rubber is good but not good enough for my application. I had some tyres on hand made with natural rubber, they are not in competition level. It must added with something filler or other in order to provide extra grip. But I have no clue on what should be mixed.
Is the norsorex the only material that can enhance natural rubber for my application? What about other I should try?
For the thread on tyre, usually we use no thread to provide max traction. thank you
RE: Reverse engineering for rubber tyre
You could add tackifiers to your compound, fe PIB for more grip. Maybe another additive that melts at 40-50°C. Don't use any waxes or anti oxidant, anti ozonant as they tend to migrate to the surface where they'll act as a non sticky layer.
To be honest I don't think you can say "NR is not good enough" just by feeling some tyres. They just might not be optimized for the one good heat.
