Paragraph starter
The thermal decomposition behaviour of composite materials is a critical factor in their long-term performance, particularly in applications involving elevated temperatures. Research, such as that by Tranchard et al. (2017), has demonstrated the utility of kinetic modelling, combining thermogravimetric analysis (TG) with Fourier Transform Infrared (FTIR) spectroscopy and numerical tools, to predict and understand the decomposition mechanisms of carbon fibre-reinforced epoxy laminates. This approach provides valuable insights into material degradation pathways, enabling designers to make more informed material selections and design for enhanced durability and safety in demanding environments.
