Abstract

The properties of prepregs are characterized in
terms of their volatile content, resin content, the degree of pre�cure, void content, tack and flow ability. The most important
properties of prepregs are resin content and volatile content. In
order to monitor the resin content, a quantitative relation to the
processing parameters such as line speed, viscosity and gap
distance between the resin up taking rollers have to be
determined.
In this study, a plain E-glass fabric with the areal weight of
300 g/m2 and an epoxy resin (CHS-EPOXY B200 M80/DCDA/2-
MEI) were used to produce the prepreg by the dipping method.
The experimental results and showed that the resin content
increased linearly with increasing the distance between rollers.
In contrast, the resin content decreased with increasing the resin
viscosity. According to our calculations, the effect of the line
speed variation on the resin content was negligibly small.
According to DoE calculations, the effect of the line speed
variation and distance between rollers on the content of volatile
was negligibly small, but the content of volatile decreased with
increasing the resin viscosity (decreased the percent solvent in
resin).
