The mechanical properties of glass-epoxy can be improved by in corporating helicoidal and pseudo orthogonal architectures observed in exoskeleton of crustaceans. When two adjacent laminas are placed with a very small angular offset, it is known as helicoidal structure and pseudo orthogonal structure is where a helical structure is placed between two unidirectional orthogonal regions. Two helicoidal structures and one pseudo orthogonal structure is designed with considering mid-plane symmetry. A

Flexural modulus and shear modulus was calculated using and was compared among all the laminates. It is observed that the mechanical performance was improved for bio-inspired laminates over the baseline laminate.
