Abstract

This work present a review on explores an overview of the flexural creep behavior of fiber reinforced polymeric composites, which are gaining considerable responsiveness due to their superior mechanical properties, lightweight nature, and versatility in various engineering applications. Flexural creep refers to the time dependent deflection or deformation of a composite material under a constant applied load, particularly in bending. The performance of these composites is affected by the type and arrangement of the reinforcement fibers, the matrix material, and the collaboration between the two phases. Fiber reinforced polymeric composites typically exhibit good initial mechanical strength; however, their long-term performance is significantly impacted by creep behavior, which can indication to undesirable deformations over time. Research has presented that the flexural creep resistance of these composites depends on factors such as fiber positioning, fiber mass fraction, and the compatibility between the fibers and polymer matrix. In particular, the inclusion of high strength fibers, such as carbon or glass, generally enhances the creep resistance, as these fibers help distribute the load more effectively. Moreover, the matrix material plays a important role in governing the creep response, as polymers with higher rigidity tend to mitigate excessive bending deformations. Understanding the flexural creep behavior of fiber reinforced polymeric composites is critical for optimizing their process parameter and ensuring their reliability in long term applications, such as in aerospace, automobile parts and construction industries. Continued research is desired to further explore the consequences of various factors on creep performance and to develop strategies for improving the durability and longevity of these advanced materials.
