Low-velocity impact resistance behaviors of bio-inspired helicoidal composite laminates with non-linear rotation angle based layups

Through evolutionary process, special biological structures (e.g. micro- or macro-scale helicoidal laminated structures) are formed naturally to resist natural enemies. With some bionic inspirations, anti-impact design of composite laminates applied for aerospace, vehicle, etc. can be stimulated by helicoidal biological structures. In the work, the Non-Linear Rotation Angle (NLRA) based bio-inspired helicoidal layups are designed to enhance the...
