These hybrid polymer materials can be applied to the textile in two principal ways.
The first method is coating on textile surfaces by using hybrid polymer materials formulation.
Hybrid polymer materials can be applied to fabric surface by spraying, transfer printing and padding.

In some cases, more than one type of balls are used for grinding raw materials.
From a microstructural point of view, the two materials show significant differences.

The paper shows that the velocities of transverse elastic waves in composite materials are functions of the fibre orientation and the fibre volume fraction.
Introduction Composite materials are ideal for structural applications where high strength-to-weight and stiffness-to-weight ratios are required.
However, it appears that the use of the SEM for analysis of wave propagation in composite materials has not been widely reported in the literature so far.
