Using natural plants such and rush and bulrush as reinforcements for composites has some advantages compared to the traditional materials like glass, carbon or Kevlar fibre.
The values of damping factors may depend on several features such as: sample dimensions, specific mass or the quantity of material from sample, elastic and damping properties of component materials.

Many investigations had suggested that the application of TiB2-TiC composite ceramics was often limited by the high costs staring materials, such as expensive TiB2 and TiC powders [2,3].
Experimental procedure Commercial available powders of B4C (99 wt.%, 200 mesh) and Ti (99 wt.%, 200 mesh) powders were used as starting materials.
One of the most evident microstructural characteristics is that there are a large number of plate-like TiB2 and hexahedron TiC grains distributed in the materials.
