Long-Term Durability of Fiber/Matrix Interfacial Bonding in Hygrothermal Environments

摘要: This study investigated the long-term durability of interfacial bond in carbon fiber /polyetheretherketone (C/PEEK) and fiber/polysulfone (C/PSF) com posites after exposure to hygrothermal environments. A single pull-out test was uti lized quantitatively determine ultimate strength (UBS) samples following exposure. Samples were tested at three temperatures for six time periods two en vironments (dry salt water). mathematical model based on nth order chemical reac tion kinetics applied describe interface. The results this indicate that C/PSF C/PEEK (380 grade) composites is significantly influenced by water, especially high temperatures. water saturation reduces as a function both temperature, with apparently reaching stabl...
