Steel pipeline systems carry about three-quarters of the world's oil and gas. Such pipelines need to be coated to prevent corrosion and erosion. An alternative to the current epoxy-based coating, a multi-layered composite coating is developed in this research. The composite coatings were made from carbon fiber-reinforced thermoplastic polymer (CFRTP) material. Uniaxial carbon fiber CF/PPS prepreg tape was utilized, where the PPS (polyphenylene sulfide) is employed as a thermoplastic (TP) matrix. Compression molding was used to manufacture three flat panels, each consisting of seven plies: UD (Unidirectional), Biaxial, and Off-axis. Samples of carbon steel were coated with multi-layered composites. The physical, mechanical, and corrosion-resistant properties of steel-composite coated samples were evaluated. A better and more promising lap-shear strength of about 58 MPa was demonstrated. When compared to the Biaxial and Off-axis samples, the UD assembly had the maximum flexural strength (420 MPa); however, the Biaxial coating has the highest corrosion resistance (445 kΩ·cm) when compared to the Off-axis and UD coatings.
钢制管道系统输送着全球约四分之三的石油和天然气。此类管道需要进行涂层处理以防止腐蚀和侵蚀。本研究开发了一种多层复合涂层，作为当前环氧基涂层的替代方案。复合涂层由碳纤维增强热塑性聚合物（CFRTP）材料制成。使用了单轴碳纤维CF/PPS预浸带，其中聚苯硫醚（PPS）用作热塑性（TP）基体。采用压缩成型制造了三块平板，每块平板由七层组成：单向（UD）、双向和偏轴。对碳钢样品进行了多层复合材料涂层处理。对钢 - 复合涂层样品的物理、机械和耐腐蚀性能进行了评估。结果表明，其搭接剪切强度约为58 MPa，表现更好且更具前景。与双向和偏轴样品相比，单向组件具有最大的弯曲强度（420 MPa）；然而，与偏轴和单向涂层相比，双向涂层具有最高的耐腐蚀性（445 kΩ·cm）。
