A method of forming a laminate for construction units and particularly laminates of fiber reinforced plastic, includes the step of locating a core between a pair of laminas, the core including a plurality of transverse openings such as a tesselated structure joined at intersections, permitting passage of an adhesive therethrough for joining the laminas. The core is of a lightweight very inexpensive material.

[ I claim:] [1.] A method of forming a laminate, comprising the steps of:positioning a core on a first lamina, the core being a tessellated sheet of material having a width and comprising separate shapes that are each connected to adjacent shapes by links of the material, the shapes being separated from each other by an interconnected web of channels that extends transversely across a surface of the first lamina, wherein each of the links is spaced from widthwise opposing surfaces of the respective shapes to avoid obstructing the channels; andapplying an adhesive to the core so that the adhesive flows widthwise through the core and transversely through the channels; andjoining a second lamina to the first lamina, with the core therebetween, using the adhesive.
