Paper Title:
Round-Hole-Fiber Distribution in Hydrophilidae Cuticle and Biomimetic Research
  Abstract

Insect cuticle possesses excellent mechanical properties, such as strength, stiffness and fracture toughness, which are closely related to its elaborate microstructures optimized through centuries’ evolution. SEM observation on Hydrophilidae cuticle shows a kind of biocomposite consisting of chitin-fiber plies and protein matrix, and the chitin-fiber plies are composed of several special arrangements. The observation also shows that there are many holes in the cuticle and the fibers passing along the brims of the holes round the holes continuously. Making use of such microstructure, a kind of biomimetic composite laminate with round-hole-fiber distribution is fabricated with preformed-hole method. The ultimate strength of the composite laminate is investigated and compared with that of the composite laminate with a hole drilled. It shows that the ultimate strength of the former is distinctly higher than that of the latter.
