Composite Materials

Composite materials are usually comprised of two constituents:

    • Reinforcement: mostly unidirectional long continuous fibers, woven fabrics, braided fabrics, non-crimp fabrics, etc.

    • Matrix: polymer (thermosetting and thermoplastic), ceramics and metals.

  • Three types of Composites depending on the matrix (resin) : PMC (polymer), CMC (ceramic), and MMC (metal).

HSCL keeps close relations with industries, and we strongly believe that understanding current problems and demands of industries gives us directions for future research.

Features and Applications of Composite Materials

Composite materials features high specific stiffness and strength, mainly attributed to carbon/glass reinforcement, and therefore are ideal candidate materials for light-weight yet strong structures, typically:

    • Aerospace structures (wing box, fuselage, helicopter rotor blade, solid rocket propellant case, etc.)

    • Wind turbine blades

    • High speed flywheel rotor for energy storage purpose, centrifuge

    • Sports goods (bicycle, hockey stick, tennis/badminton racket, etc.)

    • Sub-sea applications such as risers

    • Automobiles (bumper, body and pressure vessels)

  • Fuel tubes for nuclear power plant.

Composites Innovation

Despite that it has been half a century since the advent of composite materials, there still exists plenty room for innovations as new technologies emerge.

Our objective is to achieve lighter, stronger, more durable, and more cost effective composites, through innovations in the following fields:

    • New materials (maximize cost effectiveness)

    • New layups (maximize stiffness and strength)

    • New manufacturing process

  • New design tools
