Abstract
A composite panel includes a core having at least one core element. The core element includes a shell defining a cavity. A pair of skins sandwich the core. Each skin has a first face facing away from the core and an opposed second face facing the core. The second face has a plurality of barbs extending therefrom. The barbs penetrate the shell to secure the core element between the skins. A method for making a composite panel includes positioning a core element against a barbed face of a first skin, where the core element includes a shell defining a cavity, and pressing the core element and first skin together to force barbs of the barbed face to penetrate the shell.
