摘要
本文分析了风电叶片常用聚酯PET、PA6、PA66三种材质脱模布的力学性能、含油率以及玻璃钢界面性能的不同,并且采用扫描电镜观察了玻璃钢表面的界面形貌.结果表明:相对PET材质脱模布,PA66材质脱模具有更好的力学性能和更低的含油率,材料的拉伸强力、撕破强力性能分别提升8％与30％;不同材质脱模布玻璃钢界面性能方面无明显差异,均能够满足风电行业试用要求,其中PA66性能更加优异.
Abstract
This article analyzes the differences in mechanical properties,oil content,and interface properties of peel ply made from polyester(PET),PA6,and PA66 fabrics used in wind turbine blades.Scanning electron microscopy was employed to observe the interface morphology of the fiber-reinforced plastic surface.The results indicate that,compared to PET material peel ply,PA66 material peel ply exhibits superior mechanical properties and lower oil content.The tensile strength and tear strength of the PA66 material are improved by 8％and 30％,respectively.There is no significant difference in the interface performance among the different material peel plies,which can meet the trial requirements of the wind power industry.Among the three materials,PA66 demonstrates the best overall performance.
