摘要: 碳纤维叶片是风电叶片的重要发展方向之一,本文通过PAM-RTM工艺仿真软件对碳纤维叶片大梁结构进行了工艺仿真分析。测得玻璃纤维双轴布的三维渗透率,开展了5 m碳纤维大梁结构真空灌注工艺仿真研究,并进行了工艺试验验证。结果表明,注胶总时间计算值与实测值偏差+18%,树脂流动前沿计算值与实测值偏差最大为+18%,灌注大梁成型后未发现缺陷。

Abstract: Carbon wind turbine blade is one of the important directions of wind turbine blade, this paper aims to carry out the process simulation analysis of carbon spar cap by using PAM-RTM. The permeability test of biaxial glass fabric was conducted in order to provide three-directional permeability parameters. The process simulation analysis and the verification test of 5 meter carbon spar cap have been accomplished. After the contrasting and comparison, the deviation of total infusion time between the simulation result and verification result is about +18%. Meanwhile, the maximum value of flow front deviation between the simulation result and verification result is +18%. Also, no defect was found after observation by cutting.

Key words: carbon spar cap, PAM-RTM, process simulation analysis
