Investigation of Environmental Deterioration on Nomex Honeycomb Composites

Abstract

This study investigates the response of Nomex honeycomb, an aircraft construction material to external environmental influences. The objective is to determine the changes in mechanical properties of Nomex honeycomb, both as bare honeycomb and as part of a composite structure, due to exposure to a high- temperature, high-humidity environment. Static compression and plate shear mechanical tests were performed to assess effects of temperature and humidity. In addition, moisture uptake was determined. Shear strength was found to be only slightly affected by the test conditions; compressive strength was not affected; water uptake is 2% by weight. (Author)
