1. Introduction
Fiber-reinforced plastic (FRP) parts and especially
those made from preimpregnated fibers (prepregs) are
used in lightweight products in order to enhance product
properties because of their excellent mechanical
characteristics [1]. Because of high manufacturing costs,
that can account for up to 72 [2],
the application fields of prepregs are limited e. g. to the
aeronautics industry, where they prevail [3].
