Prepreg materials (pre-impregnated fibers) are pre-impregnated textile semi-finished products which are used for producing fiber-reinforced components. Under pressure and temperature several layers of pre-pregs are melted together. In addition to the arrangement of the prepregs, the optimum adhesion of the fiber to the reaction resin is most critical for the later stability of the complete component.
Pre-treatment of fabric using Aurora Plasma
Effective load transfer between the fiber and the matrix resin requires a clean fiber surface before the resin is applied. By pretreatment of the fiber tissue with Aurora plasma, an optimum penetration ability is achieved.
Pretreatment of fabric webs in contract manufacturing
Plasmatreat offers contract manufacturing services (toll treatment) through their 4th State Inc. subsidiary for pretreatment of tissue webs before processing to the prepreg. For this purpose, a low-pressure plasma special system with a treatment width of 1.50m (60 inch) including wrapping (roll-to-roll) is available.
