ABSTRACT:
A surface type structural component such as a wing for an aircraft is curved in space and is manufactured from a plurality of fiber wound box frames forming longitudinal and cross ribs made of fiber reinforced resin impregnated material. These box frames are formed as modular units by winding the fiber compound material onto mold bodies and assembling the mold bodies for bonding the box frames together to form a reinforcing grid structure while the box frames are still on the mold bodies. A laminated sheathing is bonded to the grid structure. Methods and apparatus including an automated assembly plant are disclosed for manufacturing the surface type structural component. The manufacturing plant includes automated handling equipment for winding the box frames onto the mold bodies, assembling the mold bodies and box frames into grid structures, forming and applying a laminate sheathing, curing and hardening the grid structure and laminate sheathing combination simultaneously under heat and pressure produced by the expanding mold bodies and removing the mold bodies from the box frames. A mold body comprising a plurality of releasably interconnecting members includes a center member with an elongate core of heat expandable material for producing the pressure for the bonding when the resin cures. The mold bodies are so constructed that they disassemble easily for removal from the box frames and subsequent reuse.
