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 rubber as a working medium Findings: During interpretation of pressure tests results according to the proposed method, it should be paid attention to the state of stresses in the wall of investigated tubular element. Ignoring fractional resistance of the rubber with sample wall, it can be obtained uniaxial stress in circumferential direction. Research limitations: Proposed research methods (non-standard NOL rings and tests using axial compressed rubber) can be applied in evaluation of fabricated long-fibrous material, e.g. determination of degree of silicone material binding. Originality/value: Proposed methods of comparative tests are easy to make and the destruction point during static tests as well as fatigue ones is clearly determined. Results of investigations serve as comparative verification of silicon-aramid material designed for oesophageal prosthesis. Tested tubular element - prototype of oesophageal prosthesis requires the reduction of reinforcing material.
