Characterization of Isotropic Composites Containing Inclusions of Specified Shapes by use of Ultrasonics In The Long Wavelength Limit
The presence of an additional heterogeneous phase, dispersed in a matrix can bring about important improvements in the properties of the original material and make it appropriate for more specific purposes. Most engineering needs require the optimization of the strength to weight ratio of materials and from this point of view, polymer composites offer excellent characteristics. This factor and others such as versatility, ease of fabrication and cost effectiveness are some of the reasons why composite plastics are rapidly gaining ground over the more usual engineering materials.
