INFLUENCE OF PLASMA TREATMENT ON THE RESULTING USEFUL PROPERTIES OF TAPES MADE OF GLASS FIBERS

Original language description

The study deals with the treatment of glass fiber tapes to form a composite suitable for further processing for example weaving, knitting, etc. It is observed the effect of plasma pretreatment, which is applied to glass fibers before the resin application. The pre-treatment affects resin adhesion to the fibers and thus the resulting mechanical properties. The resin is used to bond the fibers and to ensure the processability of the resulting tape. In order to improve the mechanical properties and overall strength of the tape, additives are added to the resin such as ash, graphite, carbiso, clays etc. Additives are also plasma modified before mixing into the resin. For plasma treatment is used the Piezobrush plasma PZ2, which is based on the direct, electric discharge at an openly operated piezoelectric transformer (PT). The Piezobrush® has been conceived to be an efficient handheld unit. At a maximum power consumption of 30 W, cold active plasma with a temperature of ~ 50 °C is generated. Detailed investigation of tensile forces like breaking force, deformation at break and initial modulus was conducted. The results showed a significant difference between the samples. Tape hardness was also measured using a macro hardness tester with Berkovicz indentor. The effect of plasma pretreatment on adhesion improvement was evaluated by examining the fiber surface structure using an electron microscope and a profilometer.
