Investigating What Effects Traditional Aviation Fluids Might Have on the Compressive Strength of Nomex® Honeycomb Core Material
Nomex core is widely used as a core material for aircraft structures such as control surfaces, radomes, engine cowls and aircraft interior structure because of its lightweight and high strength characteristics. A disadvantage of honeycomb core structures is that they are prone to fluid intrusion, and fluids often found in core structures during inspections are: engine oil, hydraulic fluid, fuel, and water. The purpose of this study is to determine if the structural properties of Nomex honeycomb core are affected by contact with a fluid. This study will use commonly used fluids such as Jet A fuel, Skydrol Hydraulic fluid, and turbine engine oil. The honeycomb core samples will be prepared i.a.w ASTM C-365/365M and soaked in a particular fluid for a period of 30 days. A compressive test will be performed and the test results will be analyzed using ANOVA and Bonferroni statistical tests.
