A Comprehensive Review on Thermal and Hygro/Hydrothermal Aging of Plant Fiber Composites: Properties, Degradation Mechanisms, and Service Life Prediction
Résumé
Recently, the growth of plant fiber‐reinforced composites (PFRCs) has a great impact on composite research and innovation. As these materials have various applications in several engineering fields, it would be of great interest to understand the multi‐physical properties of plant fiber composites under real‐life conditions. In this context, several efforts have been made to shed light on the multi‐physical properties of bio‐composites under synergetic aging environments. For this reason, the current review examines the hygro/hydrothermal and thermal aging of plant fiber polymer composites. Interestingly, the mechanical and physical (i.e., morphology chemical composition, crystallinity, thermal stability, moisture absorption…) properties of bio‐composites and their constituents are scrutinized to better understand material response under harsh environments. Several analytical models (i.e., Arrhenius, time–temperature superposition principle …) used for predicting the lifespan of the aforementioned materials are critically reviewed. This review paper is intended to provide new insights into the durability of plant fiber composites with a view to widespread industrial integration. More importantly, future directions are also provided to trigger new research areas.
