摘要

提出了一种新型的用编织碳纤维/LM-PAEK制备热塑性复合材料管的无真空方法。通过Taguchi L16设计研究了固结压力、温度、时间、加热和冷却速率的影响。在灰色关联分析（GRA）的支持下，对拉伸、抗压强度和密度结果进行分析以确定最佳参数。通过力学测试、DSC、x线摄影和SEM分析验证，优化后的试样抗拉强度为626.93 MPa，抗压强度为329.44 MPa。所开发的方法允许使用编织预浸料，使纵向纤维对齐，与长丝缠绕中的角度纤维排列相比，增强了抗拉强度。它只需要一个热压机和模具，不需要高温真空袋，气道和密封胶带。这些优点使该方法成为制造航空级复合材料管的一种简单、经济、有效的替代方法。

Optimization of high strength CF/LM-PAEK thermoplastic composite tube manufacturing parameters using the Taguchi Method and experimental verification

A novel vacuum-free method was developed for producing thermoplastic composite tubes using woven carbon fiber/LM-PAEK. The effects of consolidation pressure, temperature, time, heating, and cooling rates were investigated through a Taguchi L16 design. Tensile, compressive strength, and density results were analyzed to determine optimal parameters, supported by Grey Relational Analysis (GRA). The optimized sample, verified through mechanical testing, DSC, radiographic, and SEM analysis, achieved 626.93 MPa tensile and 329.44 MPa compressive strength. The developed method allows the use of woven prepregs, enabling longitudinal fiber alignment that enhances tensile strength compared to angled fiber arrangements in filament winding. It requires only a hot press and mold, eliminating the need for high-temperature vacuum bags, airways, and sealing tapes. These advantages make the method a simple, economical, and effective alternative for fabricating aerospace-grade composite tubes.

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
