Pre-Straining an Elastomer

Do you mean mechanically stressing it or passing it through a filter?

The question is vague.

@Lynlynch

i m sorry i was not clear abt my ques i was asked to design and fabricate a device that streches it mechanically in both directions. shall i do it just by screw mechanism or do u suggest any other mechanism.

what do u mean by passing through filter.cn u giv sum material abt dat

plz dont hesitate to reply

I've heard of stretching PVDF Polyvinylidene fluoride

That's how they make piezoelectric film (Kynar).

I don't know how you stress an elastomer. Once you remove the stretching mechanism, the material will revert back to it's original form. Remember elastomer=elastic polymer.

@Lunlynch

i just want to know about how stretching is done and about the device. I was just asked to fabricate a device for stretching the elastomer and hold it.plzz send any sketches of the device if u hav.Thanks for ur spending ur valuable time on me.

I don't know what you are trying to do, besides stretch an elastomer. Size, shape quantity, etc.

Good luck, it seems straightforward to me.

Go forth and design.

i Just want a snapshot of the device that stretches the elastomer
