From energy to aerospace, from automotive to civil engineering, fiber-reinforced polymers (FRPS) play an important role in a wide range of industries. This material offers many advantages over conventional steels, such as high strength, stiffness and light weightAt the same time, it has relatively good corrosion resistance. Long-term exposure to environmental factors, especially the hydrothermal aging process, can seriously affect the performance of FRPS. At high temperatures,The aging process accelerates, which is a challenge for structural materials that need to be used for long periods of time.
In response to this problem,The researchers conducted a series of experimental studiesIn order to explore the mechanism of hydrothermal aging on FRPS. They found that hydrothermal aging led to the irreversible degradation of the interphase of the fiber matrix, which in turn affected the mechanical properties of the material. Happily, the mechanical properties of the partially interphase were restored after re-drying, suggesting that some degree of self-healing may have occurred in the composite. This finding has important implications for understanding the performance of composites in wet environments and developing more durable materials.
The glass fiber reinforced polymer (GFRPS) used in the experiment is a material commonly used in marine, oil, and gas applications with high strength and high modulus. By using this material and a special size coating,The researchers have successfully prepared FRP materials with reversible hydrothermal effects. These results provide an important reference for in-depth understanding of the hydrothermal aging and performance recovery of composites.
FRPS plays an important role in various industries, but its durability is limited by environmental factors. Through in-depth study of the influencing mechanism of hydrothermal aging,We can better improve the design and manufacture of materialsImprove its durability and environmental adaptability.
