摘要

本研究旨在确定再生纸改性淀粉(Testliner)浸渍对细长芯细胞弹性常数的影响,以及对薄刨花板贴面蜂窝弹性常数和强度的影响。对三点弯曲梁进行了试验研究。结果表明,细长的六边形单元在正交性的主要方向上显著区分了其弹性性能和蜂窝板的弹性性能。用改性淀粉浸渍Testliner纸使细胞的弹性模量值降低约8.8%,并使蜂窝板的弹性模量的值降低至少6.9%。不考虑芯的结构形式的分析解不能用于计算具有六边形芯单元的夹芯板的弹性模量。

Starch Impregnation Effect of Testliner Paper on Stiffness of Honeycomb Panels with Slender Cells
The study aimed to determine the effect of impregnation with modified starch of recycled paper (Testliner) on elasticity constants of slender core cells and the influence on the elasticity constants and strength of honeycomb with facings made of thin particleboards. The experimental tests were carried out on beams subjected to three-point bending. It was shown that slender hexagonal cells significantly differentiate their elastic properties and elastic properties of honeycomb panels in the main directions of orthotropy. Impregnation of the Testliner paper with modified starch reduces the values of the modulus of elasticity of the cells by about 8.8 % and reduces the values of the modulus of elasticity of the honeycomb panels by at least 6.9 %. Analytical solutions that do not take into account the structural form of the core cannot be used to calculate the modulus of elasticity of sandwich panels with hexagonal core cells.
