Abstract

Abstract : The aim of this study is to evaluate the effects of type of fiber and resin on the mechanical properties of polyester composite pipe. Ortophthalic, isophthalic, vinyl ester resin was used as matrix and E, ECR (Electrical/Chemical Resistance) glass and basalt fiber were used as reinforcement and %98 silica sand was used as filler in mixtures. Samples were produced by centrifugal casting method. Samples cut from produced pipes were tested to determine stiffness, longitudinal and circumferential tensile strength. It was found that mixtures with ortophthalic resin had the highest stiffness and mixtures with vinyl ester resin had the highest circumferential tensile strength. Samples containing basalt fiber showed 10.8% higher stiffness and the highest longitudinal and 18.8% higher circumferential tensile strength when compared to mixture with E-glass fiber. Samples with ECR-glass fiber showed 20.2% higher longitudinal and 5.9% higher circumferential tensile strength. Basalt reinforced composite pipe had 2.6% less resin than E glass fiber reinforced pipe. As a result, the mechanical properties of the polyester composite pipes changed with different types of resin and fiber. Vinyl ester resin and basalt fiber reinforced pipes showed higher mechanical performance over ortophthalic resin and E-glass glass fiber reinforced pipes. Fiber-matrix bonding surfaces were investigated by SEM analysis.
