“…Composite materials are being used more often in the industrial sector and in certain applications are even pushing out conventional homogeneous materials. Their positive features such as high strength with low weight, high fatigue life, low friction, high resistance to weathering, and many others, are highly advantageous when used as a flexible connecting element [1,3,7]. However, the use of composite materials has many negative aspects, which include complicated design and manufacturing, which are mainly caused by the orthotropic properties of the material [8].…”
