Tunable Fracture Toughness in Composite Laminate
Delamination is a common failure in laminate composite structures. Delamination between plies (interplydelamination) occurs more frequently than fracturing within one ply (intraply-damage). Interply-delamination may be initiated by defects introduced during the material manufacturing process, such as porosity, resin-starved regions, damage from machining, or poor material handling. This damage can also be produced by low velocity impacts which are difficult to detect due to minimal surface damage.
