Combustion Characteristics of AdhesiveCompounds Used in the Constructionof Aircraft Cabin Materials

TL;DRAbstract

Adhesives are widely used in the aviation industry to construct lightweight and fatigue resistant aircraft cabin materials. Presently, there is no separate requirement for the flammability of adhesives, potting compounds, and fillers used in construction of cabin materials. The Flammability Standardization Task Group is an aircraft industry group that has proposed testing adhesives using the 12- and 60-second Vertical Bunsen Burner (VBB) Fire Tests requirements for cabin materials in Title 14 Code of Federal Regulations 25.853 to demonstrate that new adhesives have similar flammability to those used in certified cabin materials. Cabin materials pass or fail the VBB tests based on criteria for burn length, after-flame time, and time required for flaming drips to extinguish. The present study was conducted to determine whether the microscale combustion calorimeter (MCC) could also be used to establish similarity of aircraft adhesives, potting compounds, and fillers. To this end, thermal
