By:Samailagi Poteki Production and Consumption in the Raw Substitution is present in our everyday lives‚ and maybe much more than we once thought. Marx’s idea of commodity fetishism is loosely defined by substitutions‚ stand-ins‚ and clones of real objects and real labor. These commodities tape off and block out the public form the truth. In this essay I will peel back the label on some of these products and companies that have sold us lies time and time again. We are the martyr to the capitalist

“SMART MATERIALS” ABSTRACT The world has undergone two materials ages‚ the plastics age and the composite age‚ during the past centuries. In the midst of these two ages a new era has developed. This is the smart materials era. According to early definitions‚ smart materials are materials that respond to their environments in a timely manner. The definition of smart materials has been expanded to materials that receive‚ transmit or process a stimulus and respond

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
