摘要

本文利用热压成型技术在高温下进行的动态力学研究,重点研究了丙烯酰胺复合材料的粘弹性行为。此分析的频率范围为1 赫兹。在氮气气氛中,采用热重分析-差示扫描量热法研究了不同纤维取向的复合材料层压板的热稳定性。研究结果表明,在1 Hz以增加纤维取向的玄武岩纤维增强了酰胺类化合物。通过热重分析实验,复合材料层压板在600°C以上的温度下具有优异的热稳定性。利用傅里叶变换红外光谱(FTIR)进行分析,预测了不同纤维取向下酰胺膜的表面化学性质,并测定了纤维与基体之间的相互作用性质。复合材料层压板表面的扫描电子显微镜表明,在FTIR的帮助下,玄武岩纤维和酰胺材料之间的界面关系优越。研究结果表明,复合材料层压板可能是高性能和高温应用的良好替代品,因为它们具有极高的热稳定性和刚度。

Impact of Fiber Buildup Stacking Sequence on Thermo-Mechanical Behaviour of Natural Fiber–Reinforced Anamide Composites
This article focuses on the viscoelastic behaviour of the anamide composites using a dynamic mechanical study developed by hot compression moulding technology at higher temperatures. The frequency range for this analysis is 1 Hz. In the nitrogen atmosphere, thermogravimetry analysis differential scanning calorimetry was used to investigate the thermal stability of composite laminates with various fiber orientations. The findings showed that a glass transition temperature close to 100°C can be achieved at 1 Hz to increase the fiber orientation of the basalt fiber-enhanced anamide compounds. Through the thermo-gravimetric analysis experiments, the excellent thermal stability of composite laminates at temperatures above 600°C was conspicuous. Analysis using the Fourier transform infrared (FTIR) spectroscopy envisioned the surface chemical properties of anamide films at various fiber orientations, and the interaction properties between fiber and matrix were determined. Scanning electron microscopy on composite laminate surfaces proclaimed that the interface relationship between the basalt fiber and the anamide material is superior with FTIR findings being assisted. The findings demonstrate that composite laminates may be a good replacement for high-performance and high-temperature applications since they are thermally extremely robust with great rigidity.
