Essay Title: Material and civilization According to dictionary‚ material is anything that serves as crude or raw matter to be used or developed and civilization is an advanced state of human society‚ in which a high level of culture‚ science‚ industry‚ and government has been reached. There are basically 4 periods of materials science development in history of the world: Prehistory‚ Antiquity‚ Middle Ages‚ and Modern materials science. This essay covers the history of materials science on how different

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

Essay 15: What is the purpose of the sensorial materials? Describe the essential qualities needed in a sensorial apparatus. “The first of the child’s organs to begin functioning are his senses....instruments by which we lay hold impressions‚ and these‚ in the child’s case‚ have to become “incarnated”‚ made part of his personality.” The Absorbent Mind‚ Chapter 8‚ p. 84 A child’s journey in life begins as a physical embryo right from the time that he is in his mother’s womb

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

on Magnet materials • Alnico Magnets Alnico magnet alloy is largely comprised of Aluminum‚ Iron‚ Cobalt and Nickel. Alnico is a moderately expensive magnet material because of the Cobalt and Nickel content. Alnico magnet alloy has high maximum operating temperature and a very good corrosion resistance. Some grades of Alnico alloy can operate upwards of 1000C. Magnets made with this alloy are available in a variety of grades and dimensions and they are usually cast. Alnico magnet material is an older
