Abstract: "The growing demand for materials that can withstand extreme conditions in the aerospace and automotive industries has led to significant research on high-temperature polymeric composites. These composites are designed to maintain their structural integrity and mechanical properties at temperatures above 300 degrees Celsius. The development of these advanced materials is crucial for improving the performance and safety of aerospace and automotive components operating in extreme environments. Traditionally, thermosets were the most favorable for working in extreme environmental conditions due to their superior heat resistance and durability. Researchers have recently focused more on the development of reinforced thermoplastic composites. The specific challenges faced by researchers and engineers when developing high-temperature composites include maintaining structural integrity and mechanical properties under extreme conditions. The specific techniques used by researchers to modify and reinforce high-temperature thermoplastics for enhanced performance include the use of advanced nanofillers and their dispersion methods, fiber reinforcement strategies, flame retardant formulations, and toughening agent incorporation. The research has shown promising results in improving the mechanical, thermal, and physical performance of thermoplastics composites. However, challenges remain in predicting the long-term performance and durability of high-temperature thermoplastics in aerospace and automotive environments. These materials are essential for applications requiring thermal and chemical resistance, but their deployment in critical environments exposes them to conditions that can lead to fatigue failure through different mechanisms. These mechanisms include oxidation, thermal degradation, matrix crystallinity changes, fiber-matrix interface degradation, residual stresses, creep, and microcracking. This article aims to review the 2 approaches various authors have adopted to analyze fatigue problems, along with the characterization, modeling, and optimization methods used. Additionally, it will discuss the advancements made in this field and provide recommendations for future research."
