Assuming you’re asking from a technological, not environmental standpoint . Can we technologically put TPC’s in the bin for the next 25 years? That’s a blade that cuts both ways. Unless high performance polymers like PEEK, PEKK, PAEK, PPS, etc come down significantly in price then TPC’s are probably not going to gain much more traction in our industry. But if we don’t work to develop them then there’s zero chance of them being adopted. Much like fossil fuels thermoset resins are so damn good at what they do replacing them is really hard.
