Abstract
Key objective here was to optimize the sensor shape to minimize stress accumulation
and crack propagation around the sensor geometry inside the cured composite sample
understress. A finite element simulation model is developed for this purpose and a par-
ametric model for the sensor geometry provided better insight into the force distribution
along the fibers around the sensor element.
Consequently, different testing sample combinations were prepared, for which, fibers
were either cut or bend around the sensors and dielectric channels. Various composite
samples with different shapes of sensor dummies were also experimentally tested to
validate the computational results. CT scan models of postcure samples before and after
loading enabled indepth understanding of fiber alignment that could cause disturbances
in overall mechanical performance. The scan models also provided with sufficient
information about unwanted porosity, and
micro -crack growth inside the composite un-
der loading, which turned out to be vital for establishing a reliable simulation model and
improving parameters in manufacturing process.
In the end, the goal of the work was to transport the know -how of such pro
duction unit from experimental and flexible manufacturing system like vacuum assisted resin infu-
sion (VARI) to more sophisticated processing systems like prepreg manufacturing
where all necessary information can be provided as inputs prior to the
impregnation, thus removing error occurred due to manual handling.
