ELASTIC PROPERTIES OF POLYPROPYLENE AND POLYVINYLIDENE FLUORIDE MONOFILAMENTS AND MESHED ENDOPROSTHSES BASED ON THEM

摘要

Investigations were carried out to determine the interrelation between elastic properties of polypropylene and polyvinylidene fluoride monofilaments and meshed implants (endoprostheses) based on them that are used in reconstructive-restorative surgery, the structure of the warp-knitted endoprostheses is approximated by a mesh having rectangular cells possessing anisotropic elasticity in orthogonal directions. In this regard, for a comparison of elastic properties of filaments and filaments as constituents of meshed fabrics, a switch from the coefficient of elasticity of the mesh to Young's modulus of the filament as a constituent of the prostheses was made. It is shown that the coefficients of elasticity of the prostheses are proportional to the elasticity coefficients of polymer filaments usable for their fabrication.
