Abstract
This study investigates the influence of extreme environmental conditions on the fracture toughness of halloysite nanotube (HNT)-reinforced carbon fiber-reinforced polymer (CFRP) composites. The focus is on the impact of exposure to high humidity and its effects on the mechanical properties of the composites. The study reveals that exposure to high humidity enhances the fracture toughness of HNT-modified CFRP composites, attributed to the entrapped moisture between HNTs and the polymer matrix. This phenomenon enhances crack bridging and contributes to improved mechanical properties. Furthermore, the HNT-modified composites exhibit superior environmental degradation resistance compared to unmodified composites, demonstrating the potential of HNTs as reinforcement for advanced composite materials. The investigation underscores the significance of considering environmental factors in nanoparticle-reinforced composite design and applications, paving the way for the development of durable, high-performance materials capable of withstanding extreme conditions. The findings emphasize the need for continued research to enhance the durability and reliability of such composites, thereby offering sustainable solutions across a range of applications. This study contributes valuable insights towards the design and optimization of fracture-resistant composite materials for demanding environments.
