Evaluation of Load-Bearing Honeycomb Core Sandwich Panels
Abstract
The report describes an investigation of the performance of three-ply and five-ply paper honeycomb core sandwich panels. The core of the three-ply material consisted of metallic skins bonded to a cellular paper ply; the five- ply construction had 1/8-in.(3.2 mm) hardboard or asbestos board bonded to the metal skin which was bonded to the honeycomb paper. The panels were tested for fire safety, superficial damage, thermal conductivity, and durability. It was found that addition of backup plies did not significantly affect performance in thermal conductivity, durability, or large import loads; however, a significant increase in performance was achieved in localized superficial damage and five endurance times. The improved fire performance of the five-ply panels was still decidedly inferior to that of conventional wood stud construction. Further study should be made to determine if simple changes in the basic design of the panel are available which could bring the fire performance up to the level of conventional construction.
