Bionic Design of 3D Printed Continuous Carbon Fiber Reinforced ABS Composite with Layered Spiral Structure: Mechanical Property Data

The dataset was generated through a series of experiments involving the integration 3D printing of bionic continuous carbon fiber (CF) reinforced acrylonitrile butadiene styrene (ABS) resin composites. The process was inspired by the microstructure characteristics of the mantis shrimp propodus, known for its high mechanical strength. The bionic structure model was divided into 10 layers with a layered spiral structure, which spiraled from 0° to 45°. The 3D printing was performed using a self-built 3D printing machine with a nozzle diameter of 0.8 mm and an extrusion temperature of 240°C. The continuous carbon fiber was wrapped by the ABS resin and extruded onto the printing platform with a precision of 0.1 mm. The mass fraction of continuous carbon fiber in the ABS matrix was approximately 10 wt%. The mechanical properties, including tensile strength and impact toughness, were measured using a universal mechanical machine and an impact testing machine, respectively. Microstructural analysis was conducted using a scanning electron microscope (SEM) to observe the arrangement direction of continuous carbon fibers in the ABS matrix and the fracture surfaces.
