_________ Materials are inorganic substances which are composed of one or more metallic elements.

Metallic

Metallic materials have large number of free electrons that are said to be partially independent from their parent atoms, which allows speedy transfer of _________ charge and thermal energy.

electric

Metallic materials are of high thermal and electrical conductivities which classifies them as extremely good conductors of _________ and heat.

electricity

Metallic materials are generally opaque and reflects visible light in reaction to electromagnetic waves of light frequency signals, lustrous as we may _________.

say

Composite Materials are a mixture of two or more types of materials, mostly composed of chosen filler and a compatible ______ binder to obtain the required specific properties.

resin

Ceramic Materials consist of metallic and nonmetallic elements chemically bonded together, mostly oxides, nitrides, and ______.

carbides

Laminated or Layered Composite Materials are sandwich structures bonded using adhesive or ______ e.g. plywood, cardboard, and safety glass.

welds

Particle composites are particles suspended in a matrix of plastic, cement, rubber, or ______ e.g. concrete, molding compounds.

Unit Cell - is the basic structural unit of a crystal structure. It is generally define in terms of atom (or ion) positions within a parallelepiped volume. Valence Electrons - are electrons that are found in the outermost filled atomic shell, which participate in interatomic bonding. Wave-mechanic model - is an atomic model in which electrons are treated as being wavelike. Factors for which the Classes of ______ depend upon 1. Chemical composition 2. Mode of occurrence in nature 3. Internal Structure 4. Economic Importance 5. Industrial uses and application used in designing in Engineering Construction COMPILATION OF READING AND VIEWING MATERIALS BY: MPGALLEGOJR 3 The Fundamentals of ______ Science Mode of occurrence in nature a.Organic ______ - materials which are directly taken from carbon e.g.Plastics, synthetics, synthesized rubber b.inorganic materials - materials which are directly taken from numeral rocks e.g.Sandstone, siltstone, quarts, formalide c.Biological materials - materials that are the result of the life cycle of organism.e.g.Rawhide, bones, horns and natural rubber Properties of Engineering ______ A.Physical properties - describe the characteristics of the materials in the absence of applied force, like: 1.Dimension (L3W1H3) 2.Shape (appearance) 3.Specific gravity 4.Viscosity 5.
