Abstract:
The studies of the wave velocity during water hammer for single-layer pipes made of a composite with a liquid
flowing inside with various reinforcement schemes are presented. To develop mathematical models for calculating the wave
speed, the mathematical theory of elasticity of an anisotropic medium is used, based on the concepts of macromechanics. Using
the example of calculating a polyethylene pipe reinforced with a winding of steel fibers, an analysis was made of the results on
the effect of the percentage of fiber in the matrix of a composite material on the wave velocity during hydraulic shock. It is
shown that the results obtained are in good agreement with the other experimental and theoretical data.
Keywords:composite pipe, orthotropy, fibers, matrix, wave velocity, water hammer.
