摘要整理
本研究旨在优化真空辅助树脂注入(VARI)工艺参数,以提高复合材料试样和风力涡轮机叶片产品的力学性能,特别是弯曲强度。研究通过变化纤维体积分数(10%和20%)、真空压力(0.6 bar和0.8 bar)和催化剂用量(1%和2%)等参数进行试验,采用弯曲测试和加载测试进行评估,并运用田口方法确定最优参数组合。弯曲测试结果表明:纤维体积分数为20%时,平均弯曲强度最高,达198.20 MPa,相比10%纤维体积分数的112.20 MPa有显著提升;真空压力0.6 bar时弯曲强度为198.20 MPa,优于0.8 bar的112.20 MPa;催化剂用量1%时弯曲强度最高,达198.20 MPa,高于2%催化剂的125.13 MPa。研究结论表明,最优工艺参数组合为:纤维体积分数20%、真空压力0.6 bar、催化剂用量1%。该研究为开发轻质、高强度、环保型复合材料提供了重要指导,这些材料可作为金属的替代品应用于各类工业领域,包括风力涡轮机叶片产品的制造。
