Abstract
A composite material having a core between the layers of reinforcing material that is formed from a plurality of separate and independent cells that are not physically linked to each other as is common with honeycomb structures or cores. Each cell is hollow and is preferably hexagonal in shape. The composite material is formed by placing one or more layers of the first side of the reinforcing material on the mold surface. Said core is then placed on the reinforcing and one or more layers of the second side of the reinforcing material is then placed on top of the core. An inner mold or vacuum bag, depending upon the application and type of reinforcing material, is placed upon the second side of the reinforcing material. Resin or bonding material is then distributed directly into the area of the cells between the two sides of reinforcing material. The channels or canals defined by the space between the core cells become the resin distribution network, thus allowing the resin or bonding to spread throughout the core and saturate the reinforcing material on each side of the cells.
