Bionic Design and 3D Printing of Continuous Carbon Fiber-Reinforced Polylactic Acid Composite with Barbicel Structure of Eagle-Owl Feather: Mechanical Property Data

The process included the preparation of composite materials with varying structural designs (Model I, Model II, and Model III) and the assessment of their mechanical properties. The 3D printing was performed using a custom setup with specific temperature and speed parameters, as detailed in the experimental section.

The mechanical properties, including tensile strength and impact toughness, were measured using a universal testing machine and an impact testing machine, respectively. Microstructural analysis was conducted using a scanning electron microscope (SEM) to observe the fracture surfaces of the samples
