PANELKONSTRUKTION, ISAER TIL LUFTFARTOEJER, OG FREMGANGSMAADE TIL DENS FREMSTILLING

摘要

The composite structural panel has bottom (24), top (26) and edge layers (28) which enclose a primary core (30). The core provides additional structural strength to the panel. The edge layer (28) forms a desired panel edge angle of approximately 20 DEG to 45 DEG . The primary core (36) is trimmed at an angle (46) of approximately one-half the desired edge angle to form a first pressure reaction surface (48). A peripheral core (56) is positioned on the tapered portion of the primary core (36) so that the axis of the peripheral core (56) is perpendicular to the first pressure reaction surface (48). The peripheral core is trimmed to form a second pressure reaction surface (62) 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.
