Abstract Bamboo culm has been widely used in engineering for its high strength, lightweight, and low cost. Its outermost epidermis is a smooth dense layer that contains cellulose, silica particles, stomata acts as water mechanical barrier. Recent experimental studies have shown the higher strength than other inside regions. Still, mechanism unclear, especially how concentration (<10%) can effectively reinforce prevent inner fibers from splitting. Here, theoretical analysis combined with imaging 3D printing to investigate effect of distribution particles on composite mechanics. The anisotropic partial function bamboo skin yields toughness (>10%) randomly distributed particles. A generative artificial intelligence (AI) model inspired by developed generate particle‐reinforced composites. Besides visual similarity, it found samples show failure processes fracture identical actual epidermis. This work reveals micromechanics It illustrates AI help design bio‐inspired composites complex structure cannot be uniformly represented simple building block or optimized around local boundaries. expands space enhanced modulus, offering advantages industries where reliability critical.
