Discussion Overview

The discussion revolves around selecting low-cost, high heat-resistant plastics suitable for operating temperatures between 200°C and 300°C, with a medium strength requirement of approximately 80 MPa UTS. Participants explore material options and constraints related to the project.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • One participant mentions nylon 6/6 reinforced with 30% carbon fiber as a potential candidate for the specified requirements.
  • Another participant introduces a material called Vespal made by DuPont, noting it has fitting properties.
  • There is a question raised about whether the material must be plastic, suggesting openness to other material types.
  • A participant seeks clarification on any additional constraints beyond temperature and strength.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the best material, and multiple viewpoints regarding the necessity of using plastic remain. The discussion is ongoing and unresolved.

Contextual Notes

Participants have not specified any additional constraints beyond temperature and strength, leaving potential gaps in the material selection criteria.

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.
