Trwałość zmęczeniowa tworzywa Epidian 57

摘要: - Fatigue lives of adhesive plastics are important due to fatigue constructional glue joints. Epidian 57 composition hardened with triethylenetetramine in two ways: either 7 days at ambient temperature or 1 hour temp. 60 °C was the subject research. Cylindrical samples loaded harmonic cycles compressive stresses were tested. Temperature increase caused by variable loading determined and compared dependently on hardening method. The strain tested material under loading, number cycles, measured. An analysis viscoelastic done. It demonstrated that creep is very for process failure
