Our laboratory is the composite structure research group that focuses on the composite structural analysis and design, optimization of composite structure, repair technology, 3D reinforced composites and multi-functional composite structure application. The goals of the composite structure laboratory are to promote the understanding and the use of composite structure, to contribute significantly to the research and state of the art optimal design and manufacturing, and to provide a practical application of the research outcomes in the form of core technology of composite structure design guidelines in the future

Research vision

• We tackle challenging the practical application, to promote the understanding and use of composite structure, to contribute significantly to state of the art optimal design and manufacturing.

Research field #1 - Repair technology for composite structures

• Our research is focused on development of the repair technology for composite structures such as scarf patch method, resin injection, and micro-bolt repair method etc.

Research field #2 - 3D reinforced composites

• Development high performance of laminated composite reinforcement technology, I-fiber stitching method and dedicated equipment, and characteristic evaluation of composite specimens and structures with I-fiber stitching method.

Research field #3 – Thermoplastic composite structures

• We also put our efforts to investigate the thermoplastic composites by applying the thermoforming and in-situ technique.

Research field #4 – Multi-functional composite structures

• Our research is focused on the multi-functional composite structures such as radar-absorbing structure, anti-/de-icing based on microwave absorption technology, lightning strike protection system(LSP), and nano-composite material etc.
