Abstract
A melt processable polyacrylonitrile (PAN) terpolymer containing a UV active comonomer was spun into fibres. The as spun fibres could be processed into mats by thermal compaction of the thermoplastic fibres. The mats could then be stabilised by UV assisted cross-linking followed by thermo-oxidative cyclisation. The mats were successfully carbonised at 1500°C. The micro-structure and tensile properties of carbon fibres and the resulting mats are reported. The melt processing route has the potential to become a high volume, low cost production process for carbonaceous non-wovens for automotive composite laminate applications.
