Interfacial fracture properties of environmentally friendly hybrid systems
- 68 Downloads
Hybrid systems consist of alternating layers of metal and fiber-reinforced polymer matrix composites. These systems also referred as composite metal laminates (CML) exhibit excellent resistance to fatigue and impact loading as well as superior specific stiffness and strength . In addition, the residual strength of cracked CMLs has been shown to be greater than that of the plain metal counterpart as a result of crack bridging between the composite and metal constituents [2, 3, 4]. Traditionally, CMLs are based on thermosetting polymer matrices which normally exhibit a brittle deformation behavior and are associated with long manufacturing cycles. In contrast, thermoplastic-based CMLs offer significant advantages, including shorter processing times, high fracture toughness and the possibility of post-impact repair. However, one of the limiting factors for the development of these CMLs is the reduced availability of engineering knowledge related to their fracture mechanisms since...
