Introduction Composite materials play an increasing role in many engineering applications.
High performance, strength, stiffness and low weight are the attractive factors, which increase the use of these materials in aerospace, automobile, marine and rail industries.
Among others delamination, matrix and fibre cracking are the most common damages occurring in composite materials.

As a membrane material for a reverse osmosis filter is used polyamide and cellulose, both of these materials yield good result in case of their use.
Also plays an important role filter design, the filter is also available in the form of a straight pipe with direct winding on it filtering materials, and possibly the execution of the filter tube in the form of a spirally wound filter material [7].
It can be executed from different materials and have various forms.

Introduction Study of the effects of weathering processes on the structure and physical and mechanical properties of rocks and composite materials used in construction is very important for assessing the residual life of structural elements [1-5].
Periodic processes of freezing and thawing, saturation with water containing dissolved salts and acids, ultraviolet radiation, and periodic mechanical loads – all these phenomena lead to significant degradation of the strength properties of heterogeneous materials.
There are many NDE techniques to study the effects of the above phenomena on construction materials, and the following ones are worth noting: X-ray tomography [6-8], neutron diffraction [9] and the most widely used traditional acoustic methods [10-12].
