연구분야를 소개합니다.

Composite Materials

Metal/Polymer hybrid composites

  • Pros: Mechanical properties, low cost
  • Cons: Heavy weight (~7.9 g/cm3)
  • Pros: Lightweight, functionality
  • Cons: Mechanical properties
  • Good NVH performance
    (Noise, Vibration, Harshness)
  • Great bending stiffness to weigh ratio

Delamination of metal/polymer composite

  • The interface is an important component for composites which governs mechanical performance.
  • Interfacial properties of metal/polymer composites were tested and simulated.

Acoustic emission (AE)

  • Acoustic emission is a real-time monitoring technique to evaluate the failure of material.
  • Delamination of metal/polymer composites was observed under various loading conditions.

Formability

  • Delamination is a main fracture mechanism of composites in the forming process.
  • Formability of metal/polymer composites considering delamination was studied.
