摘要

摘要:在本研究中,将竹纤维组合物制成面板结构蜂窝夹层,并测试其作为制造垂直弹簧风力涡轮机角的物质的潜在用途。蜂窝桑威奇竹纤维的核心在面板的方向上形成正弦波。使用聚酯树脂作为该化合物上的粘合剂。制成的蜂窝夹芯板的长度为500mm,宽度为200mm,而厚面板则有两种变化,即蜂窝芯体的高度12mm和蜂窝芯体高度17mm。对这种蜂窝夹芯板进行了弯曲试验,以获得弯曲强度和刚度。在蜂窝芯高度相同的三块面板中,当蜂窝芯高度为17mm时,可以得到透镜强度的数量和面板上的最大性能,即透镜强度为0.91kg/mm2,新生数量为11,35kg/mm2关键字:蜂窝夹层,竹纤维成分,正弦波,透镜强度,新生。[UNK][UNK]摘要在这项研究中,竹纤维复合材料被制成蜂窝夹层结构面板,并将测试其作为垂直轴风力涡轮机叶片材料的能力。竹纤维蜂窝夹芯板在面板的纵向方向上具有正弦形状的芯。聚酯树脂被用作该复合材料上的粘合剂。已经制成的蜂窝板的长度为500mm,宽度为200mm。面板的厚度由两种变体组成,分别为12mm和17mm的蜂窝芯高度。通过弯曲试验对蜂窝夹芯板进行测试,以获得弯曲强度和刚度。对于每个蜂窝芯高度,三块尺寸相同的面板,在蜂窝芯高度为17mm的试样中获得了最高的弯曲强度和刚度,弯曲强度为0.91kg/mm2[UNK],刚度为11,35kg/mm。[未知]

Pembuatan dan Pengujian Panel Honeycomb Sandwich dengan Inti Berbentuk Gelombang Berbahan Komposit Serat Bambu
ABSTRAKDalam penelitian ini, komposit serat bambu dibuat menjadi panel struktur honeycomb sandwich dan diuji untuk mengukur kemungkinan pemanfaatannya sebagai bahan untuk membuat sudu turbin angin sumbu vertical. Honeycomb sanwich serat bambu yang dibuat memiliki inti (core) yang berbentuk gelombang sinus pada arah memanjang panel. Sebagai pengikat pada komposit ini digunakan resin polyester. Panel honeycomb sandwich yang dibuat memiliki panjang 500mm dan lebar 200mm, sedangkan tebal panel dibuat dengan  dua variasi, yaitu dengan tinggi inti honeycomb 12mm dan  17mm. Panel honeycomb sandwich ini diuji dengan uji bending untuk mendapatkan angka kekuatan lentur (flexural strength) dan angka kekakuan (stiffness). Dari tiga panel yang dibuat identik untuk masih-masing ketinggian inti honeycomb, diperoleh angka kekuatan lentur dan kekakuan terbesar pada panel dengan ketinggian inti honeycomb17mm, yaitu dengan angka kekuatan lentur 0,91kg/mm2 dan angka kekakuan 11,35kg/mmKata kunci: honeycomb sandwich, komposit serat bambu,gelombang sinus,kekuatan lentur, kekakuan.  ABSTRACTIn this research, bamboo fiber composite are made into honeycomb sandwich structure panel and to be tested for its ability as a material for vertical axis wind turbine blades.
