2 Page 2 of 9 Σελίδα 2 από 9 SAMPLES PREPARATION GFRP bars were prepared according to ISO :2008 (see photos in Appendix). At the two ends of each sample a steel tube was fixed as an anchoring device (Length: 300mm, Nominal Diameter: DN15 (½") / DN20 (¾") / DN25 (1"), Thickness: 2,6mm / 2,3mm / 2,0mm) filled with liquid epoxy adhesive (Type: Sikadur-52 Injection, Type N, Type LP). The samples were allowed to cure for ten days before testing for bonding between sample and liquid epoxy adhesive. GFRP bar with all its components were secured across the loading ends of a universal testing machine. The machine was programmed to apply a pull force at a rate of 15mm/min independent of the elongation of the test piece until load failure occurred (see photo of test setup in Appendix). The test temperature was maintained at 23 C 3 C. TEST RESULTS 1.
