Abstract
An aircraft floor system includes a composite panel which generally includes an inboard layer, an inboard interlock layer, a core layer, an outboard interlock layer and an outboard layer. The advanced sandwich core material may include K-Cor™ or X-Cor™ which is pinned through at least one ply of dry composite reinforcement to provide a mechanical lock between the pins and an inboard and outboard interlock layer. Bonding of the locked-in ply with the inboard and outboard results in improved structural performance and damage tolerance.
