Carbon fiber precursor with 80k tow

摘要

Spanish company MontefibreCarbon has developed a new carbon fiber polyacrylo-nitrile(PAN)precursor with a tow of 80,000 individual filaments.According to the company,the precursor is produced from a PAN formulation that can produce a carbon fiber with higher resistance,higher elastic modulus,and lower density which in turn can make more rigid and lightweight composites.MontefibreCarbon says that the new precursor could be the new standard for large-tow carbon fiber for industrial purposes,with an impact on the industry similar to the 5 0k tow,first launched more than 20 years ago.
