Experimental measurements of composite materials from the bearing structure of railway vehicles

[摘要] Composite materials belong to the category of "new materials", artificially created to meet the demands of science and technology.On the one hand, these are a perfect replacement of ferrous and nonferrous materials, and a perfect solution for a whole series of technical problems in various industrial branches, on the other hand.The composite materials represent fiber arrangements - continuous or not - from a resistant material (reinforcing elements), which are coated with a matrix, the mechanical strength of which is much lower.The Matrix maintains the desired geometrical arrangement of fibers and transmits stresses that the piece is subjected to.The present paper proposes to analyze behavioral patterns during the tests of specimens made of composite materials.
