Characterization and flexural properties of nanoclay-modified fiber reinforced polymer composites / Widia Wahyuni Amir

Fiber reinforced polymer (FRP) composites are high performance materials which are widely used in various applications, such as aircraft and high-end automobile structures. In theory, stiffer and tougher matrices provide better support to the fiber, hence enhancing the properties of the FRP composit...
