Details

Composite materials are widely used due to their lightweight, and high strength-to-weight ratio. The biggest advantage of FRP composites is the tailoring of properties based on the requirements. In this study, our objective is to utilize the biomimicry principles to maximise different mechanical properties such as tensile, bending, flexural and impact strength so that optimize designs can be used depending upon the practical applications. Through long years of evolution, species (that have survived) like fishes, nacre and mantis shrimp etc. have developed complicated higher-order helicoidal structures which are very similar to plywood-like designs. Therefore, using these designs as bio-inspiration, the current fibre orientation pattern of composites used in aerospace industries can be revolutionised to obtain higher tensile, bending, shear and impact resistance properties. We aim to accomplish comparative studies on composites with single and double helicoidal structures which are inspired by teleost fish scale’s structures. Sample fabrication using a unidirectional basalt woven will be done by hand layup process followed by the vacuum bagging method. Mechanical characterisation of both types of helicoidal composites will be performed, and their failure behaviour will be studied. Further, validation of experimental results will be done by Finite element analysis (FEA) software so that results can be applied to different structures for more general problems.
