以单向连续竹青纤维(OBF)和不饱和聚酯树脂(UP)制备了单向OBF/UP复合材料,研究了OBF含量对OBF/UP复合材料纵向静态力学性能及动态力学性能的影响,并采用SEM观察了复合材料拉伸断面处界面结合情况.结果表明:随着OBF含量的增加,OBF/UP复合材料静态力学性能呈先增加后减小趋势,当OBF含量为50wt％时,复合材料拉伸、弯曲性能最优,拉伸强度、拉伸模量、弯曲强度、弯曲模量分别达到285.52 MPa、16.06 GPa、359.80 MPa、27.32 GPa;OBF/UP复合材料存储模量随OBF含量增加呈先增加后减小趋势,当OBF含量为50wt％时,OBF/UP复合材料存储模量最大,且随着OBF含量的增加,OBF/UP复合材料玻璃化转变温度向低温方向移动,损耗峰变宽;断面处微观形貌表明,OBF含量为50wt％时,复合材料界面结合强度较好.制备的OBF/UP复合材料力学性能优良,有潜力取代玻璃纤维增强树脂复合材料在风电叶片材料、公路防护栏材料、船舶材料等领域的应用.
