In this study, bio-oil from fast pyrolysis of renewable biomass was added by the mass of phenol to synthesize bio-oil phenol formaldehyde (BPF) resins, which were used to fabricate glass fiber (GF) reinforced BPF resin (GF/BPF) composites. The properties of the BPF resin and the GF/BPF composites prepared were tested. The functional groups and thermal property of BPF resin were thoroughly investigated by Fourier transform infrared (FTIR) spectra and dynamic thermomechanical analysis (DMA). Results indicated that the addition of 20% bio-oil exhibited favorable adaptability for enhancing the stiffness and heat resistance of phenol formaldehyde (PF) resin. Besides, high-performance GF/BPF composites could be successfully prepared with the BPF resin based on hand lay-up process. The interface characteristics of GF/BPF composites were determined by the analysis of dynamic wettability (DW) and scanning electron microscopy (SEM). It exhibited that GF could be well wetted and embedded in the BPF resin with the bio-oil addition of 20%.
在本研究中，通过按苯酚质量添加可再生生物质快速热解得到的生物油来合成生物油酚醛（BPF）树脂，并用其制备玻璃纤维（GF）增强BPF树脂（GF/BPF）复合材料。对所制备的BPF树脂和GF/BPF复合材料的性能进行了测试。通过傅里叶变换红外（FTIR）光谱和动态热机械分析（DMA）对BPF树脂的官能团和热性能进行了深入研究。结果表明，添加20%生物油对提高酚醛（PF）树脂的刚度和耐热性具有良好的适应性。此外，基于手糊工艺，使用BPF树脂能够成功制备高性能的GF/BPF复合材料。通过动态润湿性（DW）分析和扫描电子显微镜（SEM）确定了GF/BPF复合材料的界面特性。结果表明，添加20%生物油时，GF能够很好地被BPF树脂润湿并嵌入其中。
