    noted that some materials exhibit more than one of the above properties and It is better to use them in combination with conventional material. Sensing Materials 1. Optical Fibers: Fiber optic sensors with crack monitoring capability have been developed by Wolff and Messelier (1992), Ansari et al (1993); Voss and Wanser (1994).It is also used to detect moisture content. A sensor for moisture detection have been developed by Michie et al (1994). 2. Piezoelectric materials: Piezoelectric

  • Training Employees On Hazardous Materials. Hazardous Materials

    Training Employees on Hazardous Materials Hazardous materials are a very important part of our environment and workplace. They can cause environmental issues or they could even cause hurt to humans and animals. However, HAZMAT is needed for production in some workplaces. There are many businesses that do not train their employees properly or not at all on hazardous materials. Anyone transferring, using, touching, or working with hazardous materials should be trained so they know what to do in case

  • Nanocrystalline Materials Essay

    706 Words  | 3 Pages

    nanocrystalline materials, it should have been explained that “nano” concept at first. Nanostructures are relatively new and interesting subject to investigate, they are in a scale which is between 0-100 nanometers (1 nanometer, nm is equal to 10-9 meter). There are some types of nanostructured materials such as lamellar (1-dimensional), filamentary (2-dimensional) and crystallites (3-dimensional). If grains of the material are made up of crystals, then “nanocrystalline materials” term is what they

  • Disadvantages Of Engineering Materials

    Introduction Engineering materials is classified into families based on their material structure, compositions, properties etc, as shown in the figure: Metals Ferrous metals: These are the metals and the alloys that are composed of high amounts of the iron content. These are the strongest materials that are available and can be used in the applications where strength of the material is compulsorily high and at a low cost and also where the weight is not a primary importance. Ferrous metals

  • Some Recyclable Materials

    686 Words  | 3 Pages

    According to Pichtel (2005), unwanted materials in the recycled process can affect in a negative way the outcomes of the recycle process and can be hazardous to workers. In addition, some industries will not accept low levels of contamination and some other industries just remove foreign material. Contamination affects the quality and recyclability of products since unwanted materials can damage the products. Recycled Paper- According to Pichtel (2005), “Paper products comprise by far the majority

  • Advantages And Disadvantages Of Materials

    these materials There are several advantages and disadvantages of the materials that have been discussed above. Natural fibers normally are renewable resource so that their cost is relatively low as compared with other synthetic fibers. With the consideration of environmental consciousness, natural fibers are biodegradable so as they can alleviate the problem of massive solid wastes produced and relief the pressure of landfills if they are used for replacing other non-degradable materials for product

  • Sintered Ceramic Materials

    density. The high sintered density can be attributed due to the small degree of agglomeration and fine nature of powder. The properties of sintered ceramic materials depend upon the sintered density and porosity of ceramic. It is well known that during sintering of homogeneous materials, the porosity decreases and the microstructures of the material develop, depending upon the morphology, agglomeration and sintering conditions. The Cu0.5Ni0.5Fe2O4 specimen sintered at 850oC has lower %relative density

  • The Material Selection For Disc

    2464 Words  | 10 Pages

    3.1 Material Selection for Disc A turbine disc rotates at high angular velocity and operates at higher temperature. High angular velocity induces higher centrifugal stress and high temperature gradient induces higher thermal stress. This operating condition demands that material used for the turbine disc should have high strength even at elevated temperature. Specifically, the tensile yield strength should be high enough to withstand centrifugal stress developed by disc and axial loading by blades

  • Advantages Of Composite Materials

    2. Composite Materials 2.1. Introduction Composites are materials consisting of two or more chemically distinct constituents having a clear interface separating them and with properties which cannot be obtained by any constituent material working individually [1]. One of the modern definitions of composite materials was given after 1990 and it says that: “A modern composite material is a system formed of at least two constituents, in which the fiber volume fraction is at least 10% and in which the
