Carbon Fiber Oxidation Oven: Center-to-ends airflow for optimal temperature uniformity resulting in consistently oxidized density across the entire tow.

Oxidation is considered to be one of the most important process steps, yet is also considered the process step that still has the greatest improvement potential. Since oxidation is an exothermic process, uniform, consistent airflow to uniformly remove heat from all tows across the web is a critical success factor. The Despatch Center to Ends Carbon Fiber Oxidation Oven produces a uniform airflow over the tows allowing the process to be operated closer to the "exotherm", increasing the chemical reaction rate. Airflow turbulence is minimized to prevent cosmetic damage to fiber tows. Consistency of process results in no skinning (uncured core) and more uniform densification across the entire tow band. Center to End airflow provides for up to 30% faster rates of oxidation than conventional cross flow or vertical down flow oven designs.
