Continuous fibers prevent structural weakness: trees

Knotholes in wood do not crack because the fibers around them are continuous.

BIOMIMICRY TAXONOMY
Summary
"There has been relatively little attempt to produce an artificial analogue to wood because wood is cheap, lightweight, tough, moldable, and easily shaped. However, when a hole is drilled in timber, it weakens the structure. The tree, however, drills no holes, even though it must disrupt the trunk's wood where a new branch pushes through. The fibers deform around a knothole, remaining continuous. George Jeronimidis of the Univ. of Reading Center for Biometrics is proposing to study how this can be used in fibrous composite materials."
