风电叶片拉挤玻板层间夹层织物性能研究

Study on Properties of Interlayer Fabric of Glass Fiber Pultruded Plate for Wind Turbine Blades

选取4种面密度均为200 g/m_(2)的玻纤织物作为拉挤玻板层间夹层织物,分别测试其导流速度和力学性能的差异。测试结果表明4种织物作为拉挤玻板层间夹层织物,在相同条件下导流速度差异为V_(A)>V_(B)>V_(D)>V_(C),即方格布A纬向的导流速度最快,经编±45°双向布C的导流速度最慢;4种织物作为拉挤玻板层间夹层织物时,拉挤板的搭接剪切性能无显著区别,双向布C作为拉挤玻板层间夹层织物可获得最佳的层间剪切性能,方格布A作为拉挤玻板层间夹层织物可获得最佳的90°抗拉强度。

Four kinds of glass fiber fabrics with area density of 200 g/m^(2) were selected as the interlayer fabric of glass fiber pultruded plate,and the differences of diversion speed and mechanical properties were tested respectively.The test results show that under the same conditions,the difference in diversion speed of four kinds of fabrics as interlayer fabrics of glass fiber pultruded plate is:V_(A)>V_(B)>V_(D)>V_(C),and the diversion speed of weft knitted square fabric A is the fastest,and that of bidirectional fabric C at warp knitted±45°is the slowest.When four kinds of fabrics are used as interlayer fabrics of glass fiber pultruded plates,there is no significant difference in lap shear properties of pultruded plates.Fabric C as the interlayer fabric of glass fiber pultruded plate can obtain the best interlaminar shear properties,and fabric A as the interlayer fabric of glass fiber pultruded plate can obtain the best 90°tensile strength.
