Impact Tolerant Paneling Material
Sandwich panels are used in many fields but have not been fully adopted in critical structural applications due to damage tolerance and safety concerns associated with debonding. This is a new type of composite sandwich panel that has superior debonding resistance and impact tolerance because of its state-of-the-art foam core.This light-weight sandwich panel contains a hybrid core consisting of a polymer matrix reinforced with a grid of hollow metallic millitubes, which increases the overall panel strength and provides resistance to buckling. Additionally, the sidewall and core are fully bonded, thereby minimizing the structural weaknesses caused by debonding. The panel is composed of lightweight materials, and the strength and weight of the panel allow it to be used for critical structural applications like automobile construction and military armor.
