Paragraph starter

Research indicates that the thermo-oxidative aging of carbon fabric composites leads to a degradation of impact properties. However, studies have shown that employing a 3D braided structure in conjunction with graphene nanoplatelet reinforcement can significantly enhance the material's resilience. For instance, a 3D braided graphene-enhanced composite retained approximately 8% higher impact strength compared to a laminated composite after prolonged exposure to elevated temperatures (Fan et al., 2014). This suggests that for design projects requiring durability in high-temperature environments, prioritizing advanced composite structures and additives is crucial for maintaining performance.
