Montefibre Carbon Unveils PAN Precursor

  • Reading time: about 4 minutes

MontefibreCarbon unveils its first carbon fibre PAN precursor; an innovative tow of 80k (80,000 individual filaments) that will be available by mid-2020. 

MontefibreCarbon’s 80k aims to be the new standard for large-tow carbon fibre for industrial purposes, and the company expects its impact on the industry to be similar to the 50k tow first launched more than 20 years ago. 

Montefibre’s carbon fibre precursor is produced from an exclusive polyacrylonitrile formulation (PAN), which enables a carbon fibre of high resistance, high elastic modulus, and low density, and which translates to very rigid and lightweight high performance composites. The initial Montefibre 80k product range will consist of the M500 and M600, both qualities for non-aerospace use, with standard modulus (SM). 

Montefibre’s M500 and M600 series with 80,000 filaments pursue cost-performance for large volume applications, providing affordable price along with superior fibre quality. Montefibre 80-M500-SM series has been designed to produce standard industrial quality carbon fibre, type T300, with a tensile strength of 500 ksi (3.5 Gpa) and a modulus of 33 msi (230 Gpa), mainly designed for use in SMC for press moulding, in pellets for injection moulding, and milled for 3D printing and construction. 

Montefibre 80-M600-SM has been engineered to produce superior quality carbon fibre, with a tensile strength of 600 ksi (4.1 Gpa) and a modulus of 34 msi (235 Gpa), mainly designed for pultrusion, UD tapes, NCF prepreg, and filament winding. In the words of Montefibre Carbon’s Research Director, PhD. María Simon, “the tests we have carried out over the last year have confirmed that the M500 and M600 series have an exceptional thermal profile that allows for high performance and low energy consumption in conventional oxidation and carbonisation lines”. 

The first production line of Montefibre 80k fibre will come into operation in mid-2020 with an annual capacity of 3,000 tonnes of PAN precursor. Two other production lines will start operating in 2021, reaching an initial capacity of 11,000 tonnes per year, which can be transformed into around 5,000 tonnes of carbon fibre. The universal carbon fibre “The new Montefibre M500 and M600 in 80k will make carbon fibre universally accessible to globally expand the substitution of steel, aluminium, and glass fibre in many applications outside the aerospace market, such as marine, construction, or automotive” says Alfonso Cirera, President of Montefibre Carbon. 

Montefibre’s challenge is to prescribe the use of carbon fibre in an easy way for any industry, “We have been surprised to see the enormous gap of knowledge that exists between manufacturers that are integrated into large carbon groups and those outside those supply chains. There is no need to complicate or create artificial barriers to the use of carbon fibre. This advanced material can be used in virtually any standard industrial process,” notes Alfonso Cirera. 

The Montefibre M500 and M600 series are not subject to export restrictions as they are not a precursor of carbon fibre for aeronautical or defense use. For this reason, composite and carbon fibre manufacturers from many countries have shown their interest in securing with Montefibre Carbon a stable and long-term supply of carbon fibre PAN precursor without relying on the vertically integrated carbon groups against whom they also compete In addition to its own development of 80K, Montefibre Carbon is jointly developing, in collaboration with the Oak Ridge National Laboratory in the United States, an ultra-wide carbon fibre, with cables of 320k and 480k, in quality M500 for industrial use, that will be launched to the market in 2021 and that is foreseen to be carbonised at a plant in Tennessee, US.
