Assignment Title / Assignment 1 - structure and characterisation of materials
In your role as a manufacturingengineer in a small manufacturing company, you have been asked by your supervisor to produce a paper on the characterisation of materials. This is to be a relatively compact document and as such requires answers in tabular or more in depth form where appropriate. The papers must address the following:
  1. State the four main groups of engineering materials, and for each give 4 examples of each.
  1. Describe the micro and macro structural nature of each group, and for each give two examples of how structural variations alter a material/products behaviour
  1. Metallic elements may be alloyed together. Give four examples of binary alloys and four of alloys that contain 3 or more elements. State the elements used to make your chosen alloys and indicate the principle properties achieved.
  1. Ceramic materials are widely used as cutting tool materials most notably as grinding wheels, abrasive papers, ‘cermet’ and ceramic ‘throwaway cutting tool tips. Briefly discuss the structural differences associated with each and consider two applications for each.
  1. Compare the principal properties required for a cutting tool such as a hacksaw blade with those of the spring on a car suspension unit. Discuss the heat treatment process and materials specification of a suitable material for each.
  1. Car body panels may be manufactured from the following materials, compare and contrast the properties, advantages and disadvantages for each.
  1. Mild steel
  2. Aluminium
  3. Carbon Fibre reinforced composites
  4. Polycarbonate
  1. Polymeric materials replace many metallic and natural materials.
  2. State two advantages and two limitations of using polymers over metallic or natural materials
  3. In terms of structure explain the differences between a thermoplastic material such as Polythene with a thermosetting material such as ‘Bakelite’
  4. Discuss the use of fillers in Nylon, Phenol Formaldehyde (Bakelite/Tufnol) and Epoxy Resins
  5. Explain why a synthetic version of natural rubber extends up to 1200% compared to 800% for its natural counterpart. (Values are approximate).
  6. List four groups of chemicals added to PVC; in each case briefly describe their purpose and quantities used.
Guidelines for Achieving Assessed Pass Criteria
You must attempt all requirements in sections 1 – 8 outlined in the previous sheet, showingappropriate evidence and analysis within all stages of those sections.
Guidelines for Achieving Assessed Merit Criteria
You must demonstrate that an effective approach to study and research has been applied with goodunderstanding of materials characterisation, showingsuitable technical knowledge and evidence of analysis relating to questions 4 – 8 describing typical industrial applications as appropriate, using an apprropriate range of sources of information.
Your presentational work must be of good standard with appropriate structure and approach in all sections.
Guidelines for Achieving Assessed Distinction Criteria
You must demonstrate that activities have been professionally managed to Distinction standard with clear evidence of in-depth analytical contentent within Sections 4 – 8
