Asphaltenes to Carbon Fiber Solution
Our Spinning Technology
CarboMat uses a modified melt spinning technique where pre-processed oil sands asphaltenes are first fed into a closed reactor and then heated and pressurized to melt the precursor. At elevated temperatures and pressures, the melt mixture is guided through a single or multi-hole spinneret to extrude thin filaments (~10-15 µm) which are later winded in a spool at high winding speeds to collect the green fibers. The green fibers then later go through a series of post-processing steps before they are finally transformed into carbon fibers.
