Surface processing of continuously moving fiber bundle using new helical coupled plasma system

journal article - other

English

We have developed a new helical coupled plasma system permitting continuous surface treatment and modification of fibers. The system is optimized for glass fiber bundles. The apparatus is provided with RF (13.56 MHz) power ranging from 20 to 500 W. Plasma chamber made from Pyrex-glass tube is 400 mm long and its inner diameter is 40 mm. Fiber supply and take-up spools are placed on a mechanical feedthrough. The bundle of glass fibers is guided along the axis of the cylindrical plasma chamber. The spools are placed in vacuum chambers connected to the plasma reactor. All system is evacuated by the vacuum system through a ball valve and a liquid nitrogen cold trap. The bundle can move by rates from 0.1 to 50 mm s-1. Some monomers as hexamethyldisiloxane and vinyltriethoxysilane were used for surface modification of glass fiber bundles in continuous regime. The argon plasma and oxygen plasma treatment of bundles was carried out as well. The processed bundles were used as reinforcements for glass fiber/polyester composite and the fiber and composite properties were compared with those of untreated fibers.
