Purpose: The aim of the work was roughness investigation of the surface of developed oesophageal prosthesis before and after texturing, to estimate its influence on future application of prosthesis. Design/methodology/approach: Linear, mechanical contact-measurement method and, for verification, optical profile measurement in confocal microscope were used in the work. Findings: The roughness investigation...
Purpose: The evaluation of modified aramid fibres - Kevlar - as reinforcement in silicon materials used in medicine. Design/methodology/approach: Samples of laminated material based on modified aramid fibres and medical silicone were made by a method of manual formation of laminates that is impregnation of reinforcement with matrix to hardening silicone process using hardening methods connected with...
Purpose: The investigations serve as comparative verification of silicone-aramid material designed for oesophageal prosthesis. Design/methodology/approach: In this work, non-standard research techniques, particularly designated for comparative tests of long-fibrous composite materials, are presented. Those tests are carried out on equipment similar to so called NOL rings test and pressure tests using...
Purpose: The aim of this work is to study of constructional model of internal prosthesis of oesophagus with determined functional features; the prosthesis will replace the upper part of the digestive system – the oesophagus. Design/methodology/approach: Constructional model of internal prosthesis of oesophagus was worked out in the basis of physiological build of oesophagus considering surgical techniques...
Purpose: Examination of elaborated composite material in terms of specific application in medicine – as internal prostheses of oesophagus. Development of the manufacturing technology of aramid-silicon laminated material and definition of the micro-cavities amount formed during production of the laminates. Design/methodology/approach: Aramid-silicon laminated material was made by a method of manual...
Purpose: Development of the manufacturing technology of aramid-silicon laminated material and define of the micro-cavities amount during production of the laminates and identification of their influence on product properties with assumed medical implantation. Design/methodology/approach: Aramid-silicon laminated material was made by method of manual formation of laminates, that is impregnation of...
Purpose: Development of the manufacturing technology of aramid-silicon laminated material. Design/methodology/approach: Aramid-silicon laminated material was made by method of manual formation of laminates, that is impregnation of reinforcement with matrix, to hardening silicone process using hardening methods connect with hot. Created material was being observed by using MEF4A light-microscope of...
