Numerical and Experimental Investigation of the Thermal Propagation Inside the Carbon Fiber Composites

Popis výsledku v původním jazyce

The infra-red non-destructive testing is a contactless method suitable for thin shells. The method is based on the non-uniform thermal excitement propagation through the materials of different thermal characteristics, as caverns, delamination or inserts. The knowledge of the thermal impulse propagation through the material velocity could be very helpful for the phase shift diagrams evaluations. Some investigations on problems of determination of the thermal wave velocity are described on this article. Several samples was made of the carbon fiber fabric saturated with polymer resin by vacuum infusion. The thickness of samples was various. The thermal propagation was measured on these samples. The heat load was applied by two methods, using the halogen lamp or a warm object of high thermal capacity and conductivity. The time delay of thermal wave was evaluated using thermograms. The velocity of propagation is evaluated as the ratio of time delay to thickness. Then the numerical simulation of heat conduction inside the samples was performed using similar conditions as during the experiments. ANSYS software have been used for numerical simulation. Finally the experimental and numerical results were compared. The limitations and usage of all the methods have been discussed.
