Polymer composites, composed of a polymer matrix reinforced with fibers or nanomaterials, have revolutionized various industries due to their superior mechanical properties, lightweight design, and chemical resistance. However, understanding their behavior under hydrothermal conditions—exposure to high temperature and moisture—is crucial for optimizing their performance in demanding applications. This article delves into the current state of research on the hydrothermal behavior of fiber and nanomaterial reinforced polymer composites, highlighting their remarkable potential and practical implications.

Hydrothermal conditions challenge the integrity of polymer composites, affecting their mechanical stability, dimensional accuracy, and long-term durability. Moisture absorption can lead to swelling, plasticization of the matrix, and degradation of the interface between the fiber or nanomaterial reinforcement and the polymer matrix. These effects can result in reduced stiffness, strength, and increased creep deformation.

The incorporation of fibers into polymer composites enhances their hydrothermal stability. Fibers provide reinforcement, restricting matrix swelling and moisture absorption. Glass fibers, carbon fibers, and aramid fibers have demonstrated excellent performance in hydrothermal environments.
