I am exploring all types of polymers to find the most suitable alternative precursor towards automotive grade carbon fibre (2 GPa, ~10$/Kg). I hv read various publications & patents around liginin, PAN/liginin, Pitch, PE...however, got an impression that resultant fibres are still far behind PAN, not even close to T300. Out of many available options, what precursor polymer seem to you the best possible candidate which can replace PAN? Will appreciate your feedback and any relevant literature/link pls feel free to share.Thanks, Abdullah Kafi
I remember to have seen rayon based and pitch based carbon fibers - but they are well known.
Most of the potential precursors you already mentioned. In my opinion it is not about precursor it is about technology for stabilization. When PAN can be stabilized under not so stringent conditions others are not. Also resource has be cheaper fur automobile to reduce fibre cost as you mentioned. Research will be needed in special structure polyolefins. Initial target should be hybrid.
Thanks Gyorgy. I agree:-) Rayon & Pitch both are old but I think Pitch is more attractive than Rayon considering high Carbon Content, high modulus & excellent conductivity. Please correct me if I am wrong.
Dear Prof Mohini, Agree & Liked your comment. I was actually searcing for a potential precursor candidate which do not need stabilisation step or a different method for stabilisation, can help to reduce significant cost associated with CAPEX or OPEX. I wonder if you can refer any paper or patent on Specialty Hybrid Poleolefin as you mentioned?
Absolutely agree. For high strength there currently is no alternative precursor which appears competitive with PAN.
Thanks Kunlin-I consider natural precursors as always good option and think lot of works to be done in this area, however, strength of cellulose/lignin based CF is still much lower than conventional PAN CF. I do not know any group reported even 2 GPa? Please feel free to share if you see any interesting literature around high strength CF ( I mean Continuous fibre, higher than 1.5 GPa) from lignin/rayon/cellulose...
You should look into cellulose and chitin fibers. I think there is a lot of work being done in the UK. Perhaps look at Steve Eichorn's work
Thanks Anthony- I will also include steve in my search...BTW pls feel free to share here or inbox me if you read any good paper in this area
