Abstract [en]

Thermal behavior of hybrid carbon/glass thin-ply laminates with different layer thickness ratios were investigated experimentally. Two different approaches were used for applying thermal loads: in one experiment small-scale external heater was attached on the surface of laminate specimen; in the second approach cyclic mechanical loading with high frequency was applied to generate internal heating within materials. In both experiments transient temperature distribution along the thickness of specimens was measured and recorded using high performance thermal imaging camera. Obtained results demonstrate temperature distribution in reference and hybrid laminate layers during the transient and steady state thermal conditions. Relatively large differences between carbon/epoxy and glass/epoxy layers were found in terms of internal heat generation and heat transfer. Parametric analysis results on reference and various hybrid lay-ups from this study could aid the lay-up design for composites in multifunctional applications with various thermal processes.
