The measurement ofdynamic mechanical properties of structural materials is of interest for at least two reasons; (a) accuratenumerical values of such intrinsic material properties are needed as input to design equations, and (b) dynamicmechanical property measurements can be used for quality control operations during fabrication and/or forperiodic in-situ inspection during the service life of the components. The increasing use of composite materialsin the aerospace, aircraft and automobile industries has brought about the need for rapid and reliableexperimental techniques to characterize their mechanical properties.

Consequently, the product designer is forced to make approximations based on similarity toclassical, or closed–form soluble problems which result in overdesigned product that may be non–competitivefrom a cost standpoint. On the other hand, the product designer may rely on physical prototyping which isgenerally expensive and increases the cost of the design process. With the proliferation of personal computersand the availability of software to aid the design process, it is no longer necessary to rely heavily on intuitionand settle for approximate solutions to real–world problems. 2

An emphasis is given in this paper to incorporate someapplications of composites in an innovative way to undergraduate students. The experience shows that this is aviable and inexpensive approach to complement the education on composite materials. Introduction Applications of fiber composite materials and sandwich structures are significant in the design andmanufacturing of aerospace vehicles.
