A STUDY ON THE FIBER METAL LAMINATED PANEL FOR BLAST-RESISTANT CONTAINER

摘要

This research focuses on the composite panel structure design and manufacture due to its cost is die dominant factor in marketing hardened unit load device (HULD). The composite panel was built by utilizing hot press manufacturing process to bond two thin metal face sheets with aramid fiber prepreg. By exposing the panel in the high humidity environments, the mechanical test showed the negligible strength degradation. In other words, the metal skin not only can protect the fiber from small energy impact as well known but also can inhibit fiber from absorbing moisture. In addition to the tensile test, the specific gravity and the bonding strength under different surface treatments were also obtained in this study. As the confidence built up from various specimen tests, several explosion tests were performed on blast-resistant and traditional LD-3 container respectively. The tests showed that HULD could withstand the blast of explosion in contrast to the non-blast-resistant container, which was totally destroyed. Clearly, the container built by fiber metal laminated panel is able to contain the Wast and protect the surrounding aircraft structure.
