Abstract

In this study, damage behavior of filament winded glass-reinforced plastic (GRP) pipes that reinforcing material mixed in different proportions of under static internal pressure was examined. Multi-walled carbon nanotubes (MWCNT) are used as reinforcing material and the medium-viscosity epoxy are used as matrix material. Free-ended internal pressure test was applied to the experiment. Test specimens were produced with six layered and ±55° winding angle. Reinforcement material was added as 0,5% and 1%. In addition, the wall thickness ratio of surface cracks on each kind of sample (w / t) was opened as 0.25 and 0.5 measure. Pure epoxy GRP pipes with same physical characteristics have been used as comparison sample. According to the geometry of the notch surface and different reinforcement ratios burst pressure values were determined and investigated.

Özet

Bu çalışmada, farklı oranlarda takviye edilmiş filaman sarım cam takviyeli plastik (CTP) boruların statik iç basınç altındaki hasar davranışları incelenmiştir. Takviye malzemesi olarak çok duvarlı karbon nanotüp (KNT), matriks malzemesi olarak da orta viskoziteli epoksi kullanılmıştır. Deneyde serbest uçlu iç basınç testi uygulanmıştır. Deney numuneleri 6 tabakalı ve ±55° sarım açılı olacak şekilde üretilmiştir. Takviye malzemesi % 0,5 ve % 1 olarak ilave edilmiştir. Ayrıca her numune çeşidine yüzey çatlağının cidar kalınlığına oranı (a/t) 0,25 ve 0,5 ölçülerinde yüzey çatlağı açılmıştır. Saf epoksi ile üretilmiş aynı fiziki özelliklere sahip CTP borular karşılaştırma için kullanılmıştır. Farklı takviye oranlarına göre ve farklı yüzey çentiği geometrisine göre patlama basınç değerleri tespit edilmiş ve değişimi incelenmiştir.
