SMART MATERIALS 1. Introduction The primary characteristic of a ‘‘smart material’’ is that it has the ability to respond to external stimuli in a technically useful and technically controlled way. The words ‘‘technically useful’’ and ‘‘technically controlled’’ are emphasized since all materials respond to external stimuli of some sort or other (as a simple example‚ all materials respond to temperature by changing their volume)‚ however‚ to be considered a ‘‘smart material’’ the response must

Composite materials A composite material consists of two or more physically and/or chemically distinct‚ suitably arranged or distributed phases‚ with an interface separating them. It has characteristics that are not depicted by any of the components in isolation Most commonly‚ composite materials have a bulk phase‚ which is continuous‚ called the matrix‚ and one dispersed‚ non-continuous‚ phase called the reinforcement‚ which is usually harder and stronger. The arrangement of the fiber in the matrix

Composite Materials A composite is a combination of two or more materials bonded together to gain some overall necessary goods. Types of composite include: laminated materials fibre composites particle composites. A laminate contains thin pieces of material fused together. Common examples are plywood and car windscreens. Wood is durable when exposed to a ductile force equivalent to its grain‚ but if the strength is across the particle it splits simply. A windscreen is made in a parallel way; two

A Full Laboratory Report on: The Detailed Microstucture of Primary Materials This report presents a study on the microstructure of 8 material samples using the proper optical microscopy techniques. Emphasis is given in sample preparation‚ the right use of transmitting and reflecting optical microscopy methods‚ and a detailed analysis of the distinct microstructure of metal‚ ceramic‚ and polymer materials. For metals and ceramics‚ preparation procedures include grinding‚ polishing‚ and surface

Building Codes Building code is a set of rules that specify the minimum acceptable level of safety for constructed objects such as buildings. The main purpose of building codes are to protect public health‚ safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate authority. The major model building codes used in the United States are developed by the

( PROD 20303 ) Materials & Manufacture Materials Selection Exercise In the lecture this week you were introduced to the idea of a systematic approach to materials selection. Within the discussion‚ a number of examples were provided of ways in which a short list of materials might be identified for a given type of product using key property criteria as the method of differentiating between possible selections. Final choice can then be made by grading the candidate materials against defined
