Kohlenstoff-Broschuere_GB.qxd 23-11-2004 08:04 Uhr Seite 2. 3 The manufacturing process of carbon and graphite materials contains the following steps: Raw material processing Mixing
The fiber placement process automatically places multiple individual prepreg tows onto a mandrel at high speed, using a numerically controlled, articulating robotic placement head to dispense, clamp, cut and restart as many as 32 tows simultaneously.
This process is called carbonization and leaves a fiber composed of long, tightly interlocked chains of carbon atoms with only a few non-carbon atoms remaining. While ZOLTEK has its own trade secrets, we're also eager to encourage a broader understanding of carbon fiber as an ideal material for commercial use.

from the carbon fiber manufacturers main PAN precursor production facility. This is a most likely scenario for an initial phase for introduction to Iceland. Estimates were collected assuming a maximum load (19,000 kg) for a 40 ft
As it does for glass fiber, sizing for carbon fiber promotes thorough fiber impregnation and bonding between the fiber and the resin. This, in turn, improves mechanical properties, such as compressive strength and interlaminar shear strength of the end product.
Carbon Revolution employs a proprietary "dry fiber" manufacturing process, allowing full control of fiber placement and material properties. Our research scientists are also working on the next generation of carbon fiber materials to continue advancing Carbon Revolution's leading single-piece carbon fiber wheel technology.
