Flash Thermography to Evaluate Porosity in Carbon Fiber Reinforced Polymer (CFRPs)

摘要: It is a fact that the presence of porosity in composites has detrimental effects on their mechanical properties. Then, due to high probability void formation during manufacturing processes, it necessary have availability non-destructive evaluation techniques, which may be able discover and distribution final parts. In recent years, flash thermography emerged as most valuable method, but still not adequately enclosed industrial enterprise. The main reason this lack sufficient quantitative data for full validation such technique. intention present work supply an overview current state-of-the-art regarding use evaluate percentage fiber reinforced composite materials latest results, are gathered by authors, porous carbon polymer laminates. To end, several coupons two different stacking sequences including amount fabricated inspected with both destructive testing techniques. Data coming from either or ultrasonics plotted against percentage, was previously estimated volumetric method. new obtained results witness efficacy thermography. Some key points need further consideration also highlighted.
