Abstract

This study experimentally investigates the manufacture of high-performance S2-glass fibre/Polyarylether ketone (PAEK) thermoplastic prepreg materials using an in-house aqueous wet powder impregnation method, with a focus on physical and mechanical testing to evaluate the production efficiency and material quality. The thermoplastic composite laminates produced exhibit remarkable mechanical and physical properties, with a high fibre volume content of up to 72 % and minimal void content. Processing pressure and time are shown to significantly influence the composite quality, with an optimal combination of 10.5 bar pressure and 20 min pressing time effectively eliminating most air voids. Mechanical evaluations, including interlaminar shear strength and flexural strength, provide insights into the distinctive performance characteristics of different laminate configurations. Additionally, certain composite laminates demonstrate impressive mechanical stability at elevated temperatures, with only a 15.9 % reduction in tensile strength, from 1760 MPa at room temperature to 1480 MPa at 250 °C, highlighting the potential of this material across a range of applications.

粉体浸渍法制备s2 -玻璃/PAEK复合材料的综合表征

本研究采用室内湿粉浸渍法制备高性能的s2 -玻璃纤维/聚芳醚酮（PAEK）热塑性预浸料，通过物理和力学测试来评估生产效率和材料质量。生产的热塑性复合层压板具有显著的机械和物理性能，纤维体积含量高达72%，空隙含量最小。加工压力和时间对复合材料的质量有显著影响，最佳组合为10.5 bar压力和20 min挤压时间，可有效消除大部分气孔。力学评估，包括层间剪切强度和弯曲强度，提供了不同层压板配置的独特性能特征的见解。此外，某些复合层压板在高温下表现出令人印象深刻的机械稳定性，抗拉强度仅降低15.9%，从室温下的1760 MPa降至250°C时的1480 MPa，突出了这种材料在一系列应用中的潜力。

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.
