Abstract
The composite structural panel has bottom, top and edge layers which enclose a primary core. The core provides additional structural strength to the panel. The edge layer forms a desired panel edge angle of approximately 20.degree. to 45.degree.. The primary core is trimmed at an angle of approximately one-half the desired edge angle to form a first pressure reaction surface. A peripheral core is positioned on the tapered portion of the primary core so that the axis of the peripheral core is perpendicular to the first pressure reaction surface. The peripheral core is trimmed to form a second pressure reaction surface beneath the edge of the panel. The structure is lightweight and resists deformation of the panel edge when the panel is cured under elevated pressure in an autoclave.
