Evaluation of a Multi-Layered Honeycomb Sandwich Concept for Use in Transportable Shelters.
Abstract
A concept of combining different honeycomb material types into one sandwich panel was evaluated. Using layers of paper and aluminum or paper and aramid honeycomb in a panel was shown to improve the impact damage resistance as compared to an all paper honeycomb panel. Various combinations of three different core types were evaluated. Specimens were tested for beam shear and compressive strength, drop impact damage resistance, and thermal conductivity. The shear and compressive tests were carried out at both room temperature and 200 F (93 C) while the impact tests and thermal conductivity measurements were conducted only at room temperature. The results demonstrate the advantage of combining layers of ductile, impact resistant core such as aramid or aluminum with low cost paper honeycomb. The impact damage resistance of multiple layered core exceeds that of full depth paper core for typical transportable shelter designs. A cost and weight analysis was conducted which demonstrated that the weight penalty and economics of this approach can be easily justified by the improved service life of shelter structures. Keywords: Nomex honeycomb, Adhesive bonding; and Impact resistance.
