Stiff material with low thermal conductivity

[Twin Turbo]

Hi,

i'm searching for a material with the following properties:

- high stiffness
- low thermal conductivity
- temperature resistance up to 150°C (not getting too soft at 150°C)
- no low friction coefficient (so no PTFE)
- good fracture behaviour (so no glass, ceramic)
- cheap

I've found some materials, but each of them doesn't meet at least one condition.

Does anyone know such a material?

A polymer-matrix/carbon-fiber composite would probably suit your needs.

check with SABIC Innovative Plastics, this website

http://www.sabic-ip.com/gep/en/Home/Home/home.html

they have many different engineering resins. Dig a little from this website page, you can search for properties and maybe find just what you need.
