Abstract: Commercial aircrafts require insulation in order to protect passengers in the cabin from thermal and acoustic loads. The conventional insulation in aircrafts consists of blankets made from layers of glass wool wrapped in foil that keeps the glass wool from being adversely affected by the environment.
There is a potential to improve the thermal and acoustic properties of the cabin by replacing the interior panels with conventional secondary insulation by new panels combined with vacuum insulation panels (VIP).
This technical paper is focusing on the study of the VIP integration into the interior panels. Firstly, the new structure solutions were defined on the basis of a requirement analysis for interior panels and VIP and theoretical analysis. Secondly, the manufacturing feasibility study for the new solutions was performed. The results showed that the new structures can be manufactured. Thirdly, the thermal properties of the new structure solutions were measured. The test results demonstrated a decrease of thermal conductivity of the new panels by a factor of 3-6 compared to the conventional solutions. Finally, the impact of the hot molding press on the vacuum maintaining inside the VIP was investigated. The trials proved that the high barrier films can withstand high-temperature and pressure conditions and that the thermal conductivity of the test specimens didn’t worsen after one year.
