Fiber and moisture toughening
Bamboo slivers exhibit delayed crack initiation and slow propagation under bending due to crack deflection toughening from both fibers and moisture.

Tensile strength of pure fiber cells is significantly greater than that of pure parenchyma cells
Higher fiber cell content and moisture content lead to later crack generation
Higher fiber cell content and moisture content lead to slower crack propagation
Both fiber and moisture contribute to toughening by deflecting fractures
