Abstract

The project focuses on developing glass fiber reinforced polymer (GFRP) composite pipes including a range of joining systems. A few of the many advantages of GFRP composite pipes are their non-corrosiveness, magnetic transparency, and high strength-to-weight ratio. As a part of this project, GFRP pipes and joints were designed, manufactured, and evaluated under static loads. Emphasis was placed in the evaluation of stress-rupture (burst pressure) of GFRP composite pipes that could withstand internal pressures as high as 5000 psi. The report also includes the design and testing of high-pressure composite joints for these pipes. In addition, the report discusses the use of Ground Penetrating Radar (GPR) for successfully detecting the FRP pipes under buried conditions. The report also includes the detection of gas leakage from buried pipes using mass spectroscopy.
