Design and manufacturing of composite tooling are crucial in producing cost
effective composite components with high quality. Aimed at identifying the
optimal design of integrally heated tools in terms of their thermal performance,
a number of design variables were investigated numerically in a previous study.
Statistical analysis of the simulation results revealed that a parallel layout
of heating channels can significantly improve the heating performance, and
channel separation should be determined according to the production requirement.
In the present work, an integrally water-heated tool is manufactured according
to the optimal design after some geometry amendments. Thermal properties of the
constituent materials of the produced tool are also measured. A numerical model
of the tool geometry is simulated with actual material properties and boundary
conditions to calculate the response variables of temperature uniformity and
heating rate. The numerical results are verified by experimental testing, using
a thermal camera and thermocouples. Good agreement between the simulation and
the experimental results confirmed the suitability of numerical simulation in
predicting the thermal performance of integrally heated tooling and the validity
of the boundary conditions.
