Damage tolerance in composite design relies heavily on:

Question

Accepted Answer

B. {'text': "Multiple thin plies in different directions providing REDUNDANT load paths — fiber breakage in one ply doesn't catastrophically reduce stiffness", 'label': 'B'}

Composites have low intrinsic ductility (~1-3% failure strain). Damage tolerance comes from ARCHITECTURE: many fibers in many directions, so when local fibers fail, neighbors pick up load. Fiber-dominated laminates are more tolerant than resin-dominated.
