Year: 2025
Type: article
Abstract: Polymer composite materials and bonded composites are now widely used in the design of major aircraft components due to their high specific properties and feasibility for joint assembly. Nevertheless, there are fire-related risks, which can significantly alter their thermal behavior. High temperatures directly influence the thermochemical and mechanical degradation of composites and bonded layers, leading to the apparition of damage phenomena such as delamination or interfacial cracking at the interface, and debonding at the bonded layer. The characterization of delamination and debonding in temperature remains critical to ensuring the integrity of aeronautical structures. This review aims to describe the mechanics leading to delamination and debonding as a consequence of thermomechanical loading. A recompilation of experimental tests used to characterize the mechanical properties of composite interfaces and bonded layers is provided. The adaptation of standard tests to high-temperature conditions is discussed, along with key findings from the literature. Limited research has focused on the characterization of fracture properties at elevated temperature due to the challenges associated with conducting experimental tests and analyzing the resulting data. Finally, a discussion about the main findings and the need for further advancements in delamination and debonding characterization at high temperatures is presented.
