Application based fabrication of composite materials

  1. 1. Prepared by Purvesh Nanavaty ME sem II Roll No. 247 Guided by Dr. V.V.Mathane
  2. 2. <ul><li>Introduction </li></ul><ul><li>PMC, CMC & MMC typical applications </li></ul><ul><li>at a glance </li></ul><ul><li>Fabrication techniques for specific application </li></ul><ul><li>Conclusion </li></ul><ul><li>References. </li></ul>
  3. 3. <ul><li>This seminar presents the current applications of PMC, MMC & CMC & their appropriate different technology available for fabrication. </li></ul><ul><li>WHEN FABRICATING components and structures from traditional construction materials, manufacturing is usually a matter of machining, molding, or joining material that is already solid and in such forms as block, rod, plank, or sheet. </li></ul>
  4. 4. <ul><li>When material and component are simultaneously manufactured, both designer and manufacturer should have a good understanding of how manufacturing conditions influence material properties , since there is often a notable processing–property dependency. In addition to working with an anisotropic material, the designer must also have a good understanding of the processing requirements of candidate raw materials and the specifics of potential manufacturing techniques to be able to estimate the final properties of the component </li></ul>

  33. 75. <ul><li>components must be designed with composites in mind from the onset of the design process. For this reason, the designer must have a good understanding of the candidate materials and must be well versed in the manufacturing techniques that may be employed. </li></ul><ul><li>Day by day, Increased No. of developments in the area of fabrication science In tune with the requirement of dimensions, strength application. </li></ul>
