Transcript

  • 1.  
  • 2.
    • Carbon fiber reinforced polymer matrix composite (CPMC) are high performance and advanced composite system that are utilized in a multitude of application .
    • Aerospace/aircraft structure.
    • Advance marine vessels
    • Car
    • Sports
    • others
  • 3.
    • Epoxy (Most commonly used)
    • Polyester
      • Such as Polyethylene Terephthalate (PET)
    • Vynilester
    • Nanoparticle (carbon fiber)
  • 4.
    • Epoxy resins are one of the matrix resins used in high performance and advance fiber composite. Due to
    • Low viscosity liquids to solid
    • Low shrinkage
    • No volatile emitted
    • Good mechanical properties
    • Good chemical resistance
    • Good adhesion to fiber reinforcement
    • Thermal stability over a wide temp. range
    • Good resistance to moisture
  • 5.
    • Carbon fiber will results in an improvement of
    • Higher temp. performance capability
    • Mechanical performance
    • Damage resistance
    • Extreme environment corrosion resistance
    • Improved dimensional control
  • 6. Table for carbon fibers Typical Properties High Strength High Modulus Ultra-High Modulus Density (g/cm 3 ) 1.8 1.9 2.0 - 2.1 Young's Modulus (GPa) 230 370 520 - 620 Tensile Strength (GPa) 2.48 1.79 1.03 - 1.31 Tensile Elongation (%) 1.1 0.5 0.2
  • 7.
    • The processing of fiber reinforced laminates can be divided into two main steps:
    • L ay–up
    • C uring
    • Curing is the drying and hardening (or polymerization) of the resin matrix of a finished composite. This may be done unaided or by applying heat and/or pressure.
    • Lay–up basically is the process of arranging fiber–reinforced layers (laminae) in a laminate and shaping the laminate to make the part desired.
  • 8.
    • Winding Operation
    • Molding Operation
  • 9.
    • The most important operation in this category is filament winding . Fibers are passed through liquid resin, and then wound onto a mandrel . After lay–up is completed, the composite is cured on the mandrel. The mandrel is then removed by melting, dissolving, breaking–out or some other method.
  • 10.
    • Molding operations are used in making a large number of common composite products.
    • Sheet molding compound ( SMC)
    • Resin transfer molding (RTM)
    • Prepreg
    • Pultrusion
    • Hand lay-up
  • 11.
    • In cars, CFRP is used in doors, hoods, fenders, chasis, and support frames for the engine and transmission.
    • In airplanes, CFRP is used in fuselage sections called barrels.
    • Other applications, racing bicycles, rackets, fishing rods,
  • 12.
    • Reduces weight.
    • Improves fuel efficiency.
    • Easier to mold and work.
    • Reduces pollution.
    • Lesser material used.
    • Longer lifetime.
    • Less maintenance.
