omprising layers of aligned chitin filaments stacked
together, the exoskeletons of many crustaceans are
analogous to fibre reinforced composites. A unique feature
of crustacean laminates is their helicoidal lay-up. Each
layer is rotated a slight angle from the layer below like the
steps of a spiral staircase – an unusual configuration that is
never considered for structural composites. Carbon fibre
reinforced epoxy with helicoidal lay-ups were fabricated
and tested to determine if they offered any advantage.
Under transverse loads, helicoidal laminates outperformed
commonly used cross-ply and quasi-isotropic laminates in
terms of peak load by up to 50%. Reasons for the improved
performance are suggested and validated by further tests
involving other composite material systems. Based on
these investigations, ideas for helicoidal laminates that can
be healed after sustaining damage will be presented.
Biography
Vincent Tan is an Associate Professor and Deputy Head at the Department
of Mechanical Engineering, National University of Singapore. His current
research projects cover multiscale modeling of heterogeneous materials,
damage in composite materials and structures and ballistics. His research
on concurrent multiscale methods and bioinspired composites have
been presented in several invited seminars. He is currently a member of
the General Council of the International Association for Computational
Mechanics and Vice President and Fellow of the Association for
Computational Mechanics, Singapore.
