摘要：以桐马酸酐甲酯改性杨木纤维(MEMA-PWF)为增强体、双酚A缩水甘油醚型环氧树脂(E51)/甲基四氢邻苯二甲酸酐(MeTHPA)为基体树脂,经热压成型制备杨木纤维增强环氧树脂复合材料。通过接触角测量、扫描电镜(SEM)分析表征了复合材料表面及断裂面结构形貌,并测试了复合材料的冲击强度、弯曲强度。实验结果表明,改性后的杨木纤维表面疏水性及其与环氧树脂基体界面相容性得到明显提高;以MEMA-PWF/环氧树脂体系制备的复合材料力学性能提高,冲击强度、弯曲强度分别达到7.95 kJ/m2、55.42 MPa,并具有较好的疏水性。
Fiber reinforced epoxy resin composites were prepared by compression molding based on poplar wood fiber modified by methyl eleostearate maleic anhydride adduct （MEMA-PWF） and bisphenol A epoxy resin/methyl tetrahydrophthalic anhydride （ES1/MeTHPA）. Surface properties and fracture morphology of the epoxy composites were characterized by a contact angle measurement and scanning electron microscopy （SEM）. The impact strength and flexural strength were tested. It was shown from the results that the surface hydrophobicity of modified fiber, the compatibility between the modified fiber with epoxy matrix, and the mechanical properties of MEMA-PWF/epoxy composites were significantly improved. The impact strength and flexural strength of the composites were 7.95 kJ/m2 and 55.42 MPa, respectively. The composites had a better hydrophobic performance.
