Filaman Sarım ile Üretilen CTP Kompozit Borularda Tabaka Sayısının Teğetsel Gerilme Dayanımına Etkisi

Abstract

Glass-reinforced plastic (GRP) composite pipes have many superior properties compared to other types of pipes. These are resistance to many chemicals, resistance to many weather conditions and resistance to UV rays, producing possibility for any size, mass production and high strength. For these reason GRP pipes are used for conducting of fluids containing chemicals, removing industrial waste and for oil and natural gas transmission lines. To determine the mechanical properties of GRP composite pipes which application areas increasing rapidly, several test methods have been developed. Hoop tensile strength of Glass reinforced plastic pipes is determined by static internal burst pressure tests according to ASTM D 1599 and hoop tensile strength tests according to ASTM D 2290. In this study, hoop tensile strength of 6, 8 and 10 layered E-glass epoxy composite pipes which are manufactured by the filament wound method for winding angle ± 55° was determined using both methods. Results obtained from both methods were evaluated in comparison with each other. Moreover, damage development of GRP composite pipes that occurs during the static internal pressure tests and hoop tensile strength tests were evaluated.
