这篇论文研究了Nomex蜂窝作为一种飞行器结构材料对外部环境影响的敏感性。它的主要内容是测定了Nomex蜂窝材料在高温高湿环境下机械性能的变化,包括纯蜂窝及复合结构中的蜂窝部分。进行了静态压缩及板的剪切机械试验来评价温度和湿度的影响。另外,测定了所吸收的水份。试验条件对剪切强度的影响是轻微的,而压缩强度不受影响。所吸收的水份占重量的2％。
This paper examines the sensitivity of the Nomex honeycomb to the external environment as an aircraft structural material. Its main content is the determination of the mechanical properties of Nomex honeycomb materials under high temperature and high humidity environment, including honeycomb parts in pure honeycomb and composite structure. Static compression and plate shear mechanical tests were conducted to evaluate the effects of temperature and humidity. In addition, the absorbed moisture was measured. The influence of the test conditions on the shear strength is slight, while the compressive strength is unaffected. The absorbed water accounts for 2% of the weight.
