“…Regarding thermal tool dimensioning, thermal simulation was used previously to calculate the optimal heat device set-point temperatures for fluid-heated RTM processes. 20 The aim of reaching the desired cure temperatures within the laminate was pursued by means of conjugate gradient algorithms and negligence of cure influence which is applicable for thin parts only.…”

Multi-zonal, electrically heated moulds for composite processing offer the potential of a direct heat introduction with low thermal lag and high energy efficiency. However, appropriate thermal dimensioning of these tools requires the consideration of the thermal response of the tool itself as well as the thermal and cure behaviour of the part, which is to date mostly estimated based on experience. To realize the full potential of this tool class, a numerical method is presented to determine a sound partitioning of the designated heating area utilizing 3D finite element cure simulation. Further, a cure simulation model of an application case is set up and validated. The capability of the numerical method to significantly increase the temperature accuracy and the degree of cure homogeneity are demonstrated in an evaluation of the numerically improved application case. Finally, the effect of the tool material on the zone allocations and temperature accuracy is studied.

“…The use of bulk sensors on composites from different technologies and principles have been widely study [4][5][6][7][8][9][10][11]. A rough classification could gather them in two main categories: 1) electrical devices and 2) optical devices.…”

“…On one hand, electrical devices take advantage of the conversion of external stimuli into an electric change, in terms of resistance, current or potential. On this classification we can find thermocouples [8,9], pressure transducers [10], piezoelectric sensors [11,19] and dielectric analysis devices (DEA) [12,13]. On the other hand, optical devices take advantage of the perturbation of a light beam, in terms of wavelength or period, to quantify an external phenomenon.…”
