Abstract

This study aims to investigate the properties of boron-modified phenolic resin (BPR) composites reinforced with glass fiber (GF) and mica, SiO₂, and glass powder (MSG) for potential aerospace applications. The BPR/MSG/GF composites exhibited improved mechanical strength, reduced shrinkage, and enhanced insulation properties at high temperatures. Specifically, exposed at 1000 °C, the impact strength increased by 108%, bending strength increased by 113%, shrinkage was reduced by 7.42%, and insulation properties were enhanced by 12.3%. Thermogravimetric analysis (TGA) revealed enhanced thermal stability, with a residue rate of 89.91% at 800 °C. The addition of glass powder, functioning as a fluxing agent, resulted in the densification of the ceramic layer. X-ray diffraction analysis (XRD) demonstrated that mica undergoes eutectic reaction with other fillers and glass powder to form the final ceramic layer. These findings indicate that BPR/MSG/GF composites can be optimized for high-performance applications requiring excellent heat resistance and mechanical strength. Further optimization of filler content and processing conditions can enhance the performance of these composites for specific applications.

增强航空航天应用中使用多填料系统的硼改性酚醛树脂复合材料的热性能和机械性能

本研究旨在探讨用玻璃纤维（GF）和云母、二氧化硅及玻璃粉（MSG）增强的硼改性酚醛树脂（BPR）复合材料在航空航天领域的潜在应用特性。BPR/MSG/GF 复合材料在高温下表现出更高的机械强度、更低的收缩率和更强的绝缘性能。具体来说，在 1000 ℃ 下，冲击强度提高了 108%，弯曲强度提高了 113%，收缩率降低了 7.42%，绝缘性能提高了 12.3%。热重分析（TGA）显示，热稳定性增强，800 °C 时的残留率为 89.91%。添加玻璃粉作为助熔剂，可使陶瓷层致密化。X 射线衍射分析（XRD）表明，云母与其他填料和玻璃粉发生共晶反应，形成最终的陶瓷层。这些研究结果表明，BPR/MSG/GF 复合材料可以进行优化，以满足高性能应用对优异耐热性和机械强度的要求。进一步优化填料含量和加工条件可以提高这些复合材料在特定应用中的性能。

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
