摘要： A method for producing a sliding board includes bonding one or more solid components with one or more enhanced structural sections to produce a core layer. A first enhanced structural section of the enhanced structural sections includes a corrugated medium. The core layer is extended between a first layer and a second layer. The first layer and/or the second layer are moved toward the core layer.
