Thermal cond. materials assign.

  1. 1. Temperature Testing of Materials:Six different materials were tested to determine the relative Thermal conductivity/insulation qualities of eachmaterial. This was done to assess the materials quality and relate this to an architectural or product designapplication eg (Cladding on a building). A small box was constructed to represent a scale model of a room in adomestic or commercial building. Each material was subjected to a heat source via a series of parallel lamps(Lamp placed on the outside of the box and directed to the side of the material being tested andtemperatures recorded inside the box). The materials were all of similar dimensional size including thickness.The materials chosen and their original cross sectional sizes were.Polymer High density Polystyrene 265 x 150 x 1.6 mm Polymethyl Methyl Acrylate (Acrylic) 265 x 150 x 1.3 mmMetal Galvanised Sheet Steel 265 x 150 x 1.0 mm Aluminium Sheet 265 x 150 x 1.0 mmTimber Manufactured Board (Plywwod) 265 x 150 x 2.3 mm Manufactured Board (MDF) 265 x 150 x 2.3 mmCeramic Glass 265 x 150 xEach piece was subjected to a continual light energy source. Measurements were taken at consistent timeintervals throughout a double period (1.5 hours) and recorded. Different materials were tested on differentdays.

  2. 2. Research Criteria Aspects 1. Strategies: Outline your strategies of collecting the information on tensile testing. What Materials, equipment procedure did you use? 2. Data Collection: What are the primary and secondary data involved in this investigation. (Describe in detail) Is this a quantitative or qualitative data collection? Is there any other way of looking at the data? Display the findings of this research graphically in at least three different ways. 3. Data Processing and Analysis: How is error or uncertainty part of data collection of this nature? How reliable is your data? Analyse the findings of your research and state how this can affect design work. Explain how this experiment can help you with your projects and your understanding of materials. How are experiments of this nature done in industry? Explain….Evaluation Criteria Aspects 1. Conclusion - Evaluation against SpecificationC The results of the testing or expert appraisal are interpreted to critically evaluate whether the product or products meet the specification.m Take studio images of your project being used in situ. Preferably by the target market group.T Testing of the project and evaluation against specification are used to determine whether the project addresses the brief/ research question successfully 2. Procedure - Evaluating the ProcedureP Evidence of a comprehensive evaluation of the procedures at each stage of the project. The advantages of the procedure, its limitations and weaknesses and their significance are commented on.Also how strong or how significantly weak the solution appears in relation to the procedure of the project. What areasneeded more time or focus.Improvements to the procedures are recommended with reference to the weaknesses and limitations identified inEvaluating the Procedure. 3. Recommendations - Recommendations to ProjectR If improvements to the data collection are recommended, modifications should address issues of precision, accuracy and reproducibility of the results.a The modifications proposed should be realistic and clearly described in detail. Modifications/ improvements to the product or products are suggested and explained (relating to the Evaluation against Specification) and free hand sketches, CAD and photographs of model are used to show possible changes graphically.
