strongest plastic in tensile

The ability of a material to

The ability of a material to resist breaking under tensile stress is one of the most important and widely measured properties of materials used in structural applications. I think Acetal Copolymer with 30% Glass Fiber has the greatest tensile strength. The ultimate tensile strength for it is 110 Mpa. man lift rental

Has anybody found good shear

Has anybody found good shear strength data for polymers ?

RE: strongest plastic in tensile

Yes, it probably was a typo. Just looked again the NI 40CF tensile is 32,000psi. I had just done a search so I had no experience with the stuff. I did mold some 60% glass filled nylon with a flex mod of 2 million. I was molding plastic knives that would cut copper wire.
I think it was an LNP Thermocomp something. It molded fine but I had to be careful with the sprues and runners. When they broke they were very sharp. This stuff did not bend at all until it broke.

Um, sorry to point it out, but I think the decimal's in the wrong place on that 6/12 call, Bruce. That's 17,500 psi, not 175,000.

Bruce, is that resin expensive, difficult to process, or any oddities?

Are you using it for anything?

I need to find a plastic nearly as strong in tensile as steel. ;)

Couldn't delete that last post, so...

How about QCI-15CF by Quantum Composites? It is stated as 48,000 psi. It is Polyimide based (Yes, imide, not amide) with 55% long carbon fiber.

RE: strongest plastic in tensile

How about a fully cross-linked PPS with 50% long carbon fiber?

RE: strongest plastic in tensile

Strongest I found is a nylon 6/10 at 175,000psi at break.
Polyone NI 10CF/15T

RE: strongest plastic in tensile

That should be UHMW PE, since they make ballistic vests with it now days.Rick.
