- Abstract
- Fracture characteristics of monolithic aluminum, fiber reinforced plastics and glass fiber/aluminum hybrid laminates under tensile loads have been evaluated using plain coupon and single-edge-notched specimens. Elastic modulus and ultimate tensile strength of GFMLs showed different characteristic behaviors according to the fiber orientation and composition ratio. Fracture toughness of A-GFML-UD which were determined as parameters of KIC and GIC based on critical load were similar to those of GFRP-UD and much higher than monolithic Al. Therefore, A-GFML-UD presented superior fracture toughness and prominent damage tolerance in comparison to its constituent Al.
