Title:
エネルギーを吸収する複合パネル
Document Type and Number:
Japanese Patent JP7281313
Kind Code:
B2
Abstract:
Typical composite panels are brittle and unable to support transverse pressure loads that might be imposed on the panels. For example, when used around fuel tanks of a vehicle, typical composite panels are unable to support transverse pressure loads that might be imposed on the fuel tanks during a crash of the vehicle or a ballistic impact to the fuel tanks. In the embodiments described herein, panels include face sheets that are bonded to a foam core. The foam core includes a corrugated core sheet that is formed from a highly ductile material, such as polyethylene or aluminum. When a transverse pressure load is imposed on the panel, core crush of the foam occurs as the core sheet elongates from its original corrugated shape to a curved shape during deformation. This allows the panel to dissipate the energy of the transverse pressure load applied to the panel.
