Ceramicfiberreinforcedpolymer

  1. 2. <ul><li>Carbon fiber reinforced polymer matrix composite (CPMC) are high performance and advanced composite system that are utilized in a multitude of application . </li></ul><ul><li>Aerospace/aircraft structure. </li></ul><ul><li>Advance marine vessels </li></ul><ul><li>Car </li></ul><ul><li>Sports </li></ul><ul><li>others </li></ul>
  2. 3. <ul><li>Epoxy (Most commonly used) </li></ul><ul><li>Polyester </li></ul><ul><ul><li>Such as Polyethylene Terephthalate (PET) </li></ul></ul><ul><li>Vynilester </li></ul><ul><li>Nanoparticle (carbon fiber) </li></ul>
  3. 4. <ul><li>Epoxy resins are one of the matrix resins used in high performance and advance fiber composite. Due to </li></ul><ul><li>Low viscosity liquids to solid </li></ul><ul><li>Low shrinkage </li></ul><ul><li>No volatile emitted </li></ul><ul><li>Good mechanical properties </li></ul><ul><li>Good chemical resistance </li></ul><ul><li>Good adhesion to fiber reinforcement </li></ul><ul><li>Thermal stability over a wide temp. range </li></ul><ul><li>Good resistance to moisture </li></ul>
  4. 5. <ul><li>Carbon fiber will results in an improvement of </li></ul><ul><li>Higher temp. performance capability </li></ul><ul><li>Mechanical performance </li></ul><ul><li>Damage resistance </li></ul><ul><li>Extreme environment corrosion resistance </li></ul><ul><li>Improved dimensional control </li></ul>
  5. 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
  6. 7. <ul><li>The processing of fiber reinforced laminates can be divided into two main steps: </li></ul><ul><li>L ay–up </li></ul><ul><li>C uring </li></ul><ul><li>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. </li></ul><ul><li>Lay–up basically is the process of arranging fiber–reinforced layers (laminae) in a laminate and shaping the laminate to make the part desired. </li></ul>
  7. 8. <ul><li>Winding Operation </li></ul><ul><li>Molding Operation </li></ul>
  8. 9. <ul><li>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. </li></ul>
  9. 10. <ul><li>Molding operations are used in making a large number of common composite products. </li></ul><ul><li>Sheet molding compound ( SMC) </li></ul><ul><li>Resin transfer molding (RTM) </li></ul><ul><li>Prepreg </li></ul><ul><li>Pultrusion </li></ul><ul><li>Hand lay-up </li></ul>
  10. 11. <ul><li>In cars, CFRP is used in doors, hoods, fenders, chasis, and support frames for the engine and transmission. </li></ul><ul><li>In airplanes, CFRP is used in fuselage sections called barrels. </li></ul><ul><li>Other applications, racing bicycles, rackets, fishing rods, </li></ul>
  11. 12. <ul><li>Reduces weight. </li></ul><ul><li>Improves fuel efficiency. </li></ul><ul><li>Easier to mold and work. </li></ul><ul><li>Reduces pollution. </li></ul><ul><li>Lesser material used. </li></ul><ul><li>Longer lifetime. </li></ul><ul><li>Less maintenance. </li></ul>A car’s pollution
