plastic or composite material search 1

[feb14]

I have a part that sees a lot of impact and torsion during operation. I need to make this part out of some plastic or composite with dielectric strength in the range of 380-450v/mil and below are the anticipated mechanical specs:
Tensile strength: 25000-35000 psi
impact strength 20-30 ft-lb/in
compressive strength 19000-25000 psi
flexural strength 40000-55000 psi

This material will be compression molded and the part is fairly intricate.

Can anyone please help.

Thanks

One possible candidate is Ryton from Conoco Phillips. The only property lacking is the impact values. I would give them a call for any insight on improved impact values.
