Hello,
I'm currently making a life cycle assessment for a liquid hydrogen tank.
One of the materials considered is a carbon fibre reinforced PEEK.
However, there is not a lot of data about the environmental impact of the polymer. Indeed, the only article I have found is the one from Daniel GARRAIN (which served as a reference for the Idemat database).
(PDF) The environmental behaviour of PEEK as an innovative material in a new portable hydrogen fuel cell (researchgate.net)
If any of you have data about it, I would be interested in exchanging with you.
Regards,
