Chapter 16 Composites - BGU
577Chapter 16CompositesWith a knowledge of the various types of Composites ,as well as an understanding of the dependence oftheir behaviors on the characteristics, relative amounts,geometry/distribution, and properties of the con-stituent phases, it is possible to design materials withproperty combinations that are better than thosefound in the metal alloys, ceramics, and polymericmaterials. For example, in Design Example , wediscuss how a tubular shaft is designed that meetsspecified stiffness STUDYComposites?One relatively complex composite structure is the modern ski. In this illustration, a cross section of a high-performancesnow ski, are shown the various components. The function of each component is noted, as well as the material that is used inits construction. (Courtesy of Evolution Ski Company, Salt Lake City, Utah.)Bidirectional layers. 45 fiberglass.
