Study on the Optimization Mechanism of Hollow Cylindrical Structures in Aluminum 3D Composite Panels for Peel Strength and Flexural Stress

Direct Answer: This research investigates how the hollow cylindrical core geometry in aluminum 3D composite panels enhances peel strength and flexural stress resistance. The cylindrical structure creates mechanical interlocking at the core-skin interface, distributes peeling forces uniformly, and reduces stress concentrations during bending, thereby optimizing the panel’s structural integrity and durability.

Research Focus and Structural Mechanics

The study examines the role of hollow cylindrical units in load transfer between composite layers. Unlike solid or flat cores, the cylindrical void pattern provides staged deformation and controlled energy absorption under mechanical loads, directly improving peel resistance and bending stiffness.

Key Optimization Mechanisms

  • Peel Strength Enhancement: Hollow cylinders promote a multi-point interlocking effect that delays delamination and redistributes peeling stresses away from bond lines.
  • Flexural Stress Distribution: The curved internal surfaces redirect bending stresses laterally, reducing peak tensile and compressive strains at the face sheets.
  • Geometric Tuning: Cylinder diameter, wall thickness, and spacing can be engineered to match specific structural requirements without adding weight.
