Description
Summary:Theoretical and experimental results for determining thermal diffusivity components in anisotropic Carbon Fiber Reinforced Plastic laminates up to 5 mm thick are presented. The effectiveness of the theory is evaluated by using a 3D numerical model. IR thermographic implementation of the Parker's technique has been used for determining transverse diffusivity. Both spot- and slit-mask techniques have been applied for analyzing thermal diffusivity components.
