Harper Launches Advanced Oxidation Ovens for Carbon Fibre Processing

11 April 2011

Harper International has launched a new generation of custom oxidation ovens for the processing of carbon fibre available at 300mm to greater than 4000mm tow band widths.

As a key feature, Harper has developed proprietary atmospheric seals based on its experience in building systems for atmospherically controlled thermal processes. Harper say that these unique seals reduce fugitive emissions, increase the active volume of the oven, and offer reduced energy consumption over alternatives.

According to Harper, these and other technology advancements equal faster oxidation, improved velocity uniformity and velocity range capability, assurance of temperature uniformity throughout a variety of flow rates, and optimal control of the reaction for the customer's product to ensure fibre quality.

""Through our many decades of experiences in the carbon fibre industry and trusted customer relationships, Harper has identified the growing need for an enhanced solution in the oxidation processing step. The existing technology is simply outdated and no longer sufficient,"" commented Robert Blackmon, Vice President, Process Systems Division at Harper. ""The unique technology enhancements incorporated in our oxidation ovens will help our customers efficiently and effectively meet advancing production needs.""
