In the first part of this two-part comprehensive study, mechanical properties and machinability characteristic of filament wound hybrid composite pipes with various stacking sequences of glass and carbon fibers (Glass-Carbon-Glass (GCG), Carbon-Glass-Glass (CGG), and Glass-Glass-Carbon (GGC)) were investigated experimentally. In order to determine the mechanical properties of the pipes, hardness test (Shore D), ring tensile test (ASTM D2290), and burst test (ASTM D1599) were carried out. Machinability tests were performed at various feed rates (50, 150, 250 and 350 mm/min) and spindle speeds (796, 1592, 2388 and 3184 rpm) using with and without a back-up. The results showed that stacking of the carbon layer between two glass layers (GCG) presented better performance in terms of mechanical properties and machinability characteristic. The maximum ring tensile stress of GCG specimen is 27% and 19% higher than those of GGC and CGG specimens, respectively. On the other hand, the lowest thrust forces measured during the drilling of GCG specimen while the GGC represented highest values. In addition, the use of back-up led to an increase in thrust force. The highest increase was observed in GGC sample. In GGC sample, a change in a spindle speed increased thrust force by 18–35%, while a change in feed rate increased thrust force by 20–30%.

Composite structures used in many engineering fields are produced using different production methods according to the design characteristic. The filament winding (FW) method, one of the most important of these production techniques, is preferred in the manufacturing of high-pressure vessels, pressure pipelines, and construction components. Composite pipes produced by the FW method are assembled using various processing methods depending on their usage. Drilling is one of the most used method among these processing techniques. The drilling-induced damages negatively affect the mechanical properties of the composite pipes during service. Therefore, it is important to determine the optimum cutting parameters and a suitable back-up material so that minimal damage occurs during the drilling process. In this study, firstly, mechanical properties of the glass fiber reinforced polymer (GFRP) produced by the FW method at ± 55° configuration were determined and damage characteristic based on ring tensile test was analyzed. Then, the effects of back-up use on the drilling machinability of FW GFRP pipes were investigated. Results showed that back-up use in drilling composite pipes plays a key role in reducing delamination, borehole damages, and surface roughness although it leads to occur higher thrust forces. Also, it helps prevent the propagation of interlaminar cracks around the hole.
