Aramid webs are technical fabrics which are used amongst other areas in the provision of high-performance tires, shot-blasting, heat-resistant textiles or for reinforcing components.
They are processed in injection molding machines, in continuous extrusion systems and in autoclaves (see also “Production of Prepregs”).
Plasma pre-treatment significantly improves the wettability and thus the bonding of the fabric to the plastic. This engineered Aurora plasma functionalization process allows a wide range of new material combinations. The improvement in the fiber adhesion leads to an improvement in the stability of the component.
Pre-treatment of fabric webs in contract manufacturing
Plasmatreat offers pre-treatment of fabric webs through the contract manufacturing/toll treatment division (4th State, Inc.) before processing to prepreg. For this purpose, a low-pressure plasma special system with a treatment width of 1.50m (60inch) including wrapping (roll-to-roll) is available.

Put Openair-Plasma® to the test with our rental and test systems.
Plasmatreat has further expanded its international network and founded the subsidiary Plasmatreat Schweiz AG. The company has been managed by Klaus Kresser since August 1, 2020.
Plasma moves into the center for professional know-how transfer.
As the innovation leader in plasma-based surface treatment Plasmatreat has been sharing its know-how with the industry for 25 years. The newly founded „Plasmatreat Academy” now combines a wide array of educational programs under one roof and with one common goal: facilitating an in-depth dialog with customers, suppliers, science and research.
The treatment with Openair-Plasma® brings about a targeted, site-selective change in surface properties. In industrial applications, this improves adhesion and normally incompatible polymers can be reliably bonded. Dr. Alexander Knospe demonstrates the possibilities of plasma treatment in the plastics industry and provides insights into the function and advantages of this technology
