Interactive Manufacturing Process Parameter Controll

Abstract

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. Tolerances in the chemical composition of the matrix or simple aging aspects can influence the crosslinking reaction while typical weight tolerances of the fibre product may affect the fibre content, the laminate thickness or even the global geometrical shape of the composite component through the so called “Spring-In” phenomenon. Interactively controlling the curing step is a promising approach to solve most of the above mentioned problems.
