Characterization of Isotropic Composites Containing Inclusions of Specified Shapes by use of Ultrasonics In The Long Wavelength Limit

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