Abstrakt: Cold water pipes (CWP) used in ocean thermal energy conversion installations must be able to withstand wave loads, deep seawater currents, and the weight of the pipe itself. Seawater currents shake the cold water pipe in a horizontal direction which causes the pipe to experience bending loads and the structure of the pipe material will experience tensile-compressive loads. So that it is required the properties of pipe material such high strength and better flexibility that it is not easily broken. In the material selection, High Density Polyethylene cold water pipe material reinforced with glass fiber is suitable for CWP material and corrosion-resistant as well. The formation of glass fiber reinforced High Density Polyethylene composite materials, which using hot press molds to obtain better results of combining High Density Polyethylene fiber and matrix and increasing resistance to tensile loads. The results of the tensile test of the material formed by hot pressing from High Density Polyethylene composite with fiberglass, indicating that the toughness and strain of the material with short fibers were better than that of long fibers. In short fiber, there is an increase in tensile strength by 2.7%, toughness with 42%, and strain by 35.2%. This increase in toughness and strain is required for CWP, in order to the use of short fibers becomes more appropriate for CWP construction. The improved toughness of this short fiber fiberglass provides an excellent basis to produce cold water pipe materials in Ocean Thermal Energy Conversion installations. The mechanical properties of short fibers High Density Polyethylene composites will be able to accept tensile loads from currents, waves and weight from the cold water pipe itself in the cold water pipe construction.
