Fungal Resistance of Nonmetallic Honeycomb Core Materials for Shelter Panels
Abstract:
Commercial and military shelter-grade honeycomb core structure materials were evaluated to determine their resistance to biodeterioration. These materials were bio-susceptible not only to fungi, but to termites as well. Recommendations were made to lengthen their use life by addition of fungicides to kraft paper and adhesive materials, by use of inherently bioresistant materials, and by employment of approved pesticide control techniques. As a result of these studies, 1 the specification fungal resistance test procedure was upgraded, 2 a data base for fungal resistance of military shelter grade honeycomb was established, and 3 production honeycomb core materials were evaluated for compliance with upgraded fungal resistance requirements.
