SUMMARY

The discussion focuses on selecting low-cost, high heat-resistant plastics suitable for operating temperatures between 200°C and 300°C, with a medium strength of approximately 80 MPa UTS. Participants identified nylon 6/6 reinforced with 30% carbon fiber as a viable option, alongside DuPont's Vespal, which meets the desired performance criteria. The conversation also opened the possibility of exploring materials beyond plastics, although the initial assumption was to focus on plastic solutions.

PREREQUISITES
  • Understanding of material properties, specifically heat resistance and tensile strength.
  • Familiarity with nylon 6/6 and its composite variations.
  • Knowledge of DuPont's Vespal and its applications.
  • Basic concepts of material selection for engineering projects.
NEXT STEPS
  • Research the mechanical properties and applications of nylon 6/6 reinforced with carbon fiber.
  • Investigate DuPont's Vespal, including its specifications and use cases.
  • Explore alternative materials that offer high heat resistance and low cost, such as certain ceramics or metals.
  • Examine the trade-offs between plastic and non-plastic materials for high-temperature applications.
USEFUL FOR

Engineers, material scientists, and product designers seeking cost-effective materials for high-temperature applications in their projects.

Hello,

For a current project, I am searching for high operating temperature (200C-300C), Medium Strength (~80 Mpa UTS) and low cost plastics (or at least not extremely expensive).

So far the closest I found is nylon 6/6 reinforced with 30% carbon fiber. I also found something called Vespal made by dupont, with fitting properties.

Inexpensive AND extreme performance? Does it have to be plastic?
 
Well, not necessarily I just assumed the material would be a plastic. Any suggestions?

T, UTS --- any other constraints?
 
no, that's about it.
