Interactive Manufacturing Process Parameter Control

open access: yes, 2012
The most critical step within the process chain is the curing of the matrix because here the different semi-finished products are transformed into a completely new compound material. In case of thermoset matrix systems all geometrical characteristics of the produced composite component are frozen as well.
