Fuselage

During World War I, cellulose acetate replaced the highly flammable cellulose nitrate coating on airplane wings and the fuselage fabrics. After World War I, it found extensive use in photographic and x-ray films, spun fibers, and mol ding plastics.

Monocoque structure fabricated by molding wood veneer with glue to shape under pressure was successfully used as early as 1916 in the LWF Model V complete molded fuselage and probably most famously in the monocoque fuselage... 

The Mosquito was a laminated wood monocoque design that although unusual, was not new. More uniquely, the monocoque shell was fabricated by gluing plywood skins to balsa wood core. This construction foreshadowed the popular honeycomb core/facesheet aluminum and composite designs of later years. Fuselage halves of the Mosquito were formed in closed wooden female tools (tools... 

Local repair of delamination originally caused by non-durable surface treatment is only temporarily successful at best. The surface treatment on the unrepaired portion of the assembly remains susceptible to attack and the area of delamination will likely continue to grow once the assembly is put back into service and exposed to moist conditions. Replacement or complete remanufacture of the component is the only way to permanently address this type of damage. However, time-limited repairs using bonded or mechanical methods can be used to extend the life of the component until a major overhaul is scheduled. In some cases such as widespread disbond of fuselage doublers, mechanical repairs (rivets and fastened doublers) and continued inspection are used to extend the life of the skin indefinitely because of the high cost of replacement.

Skins with bonded doublers have been used successfully on a large number of civil aircraft and are still used on new designs. The only widespread in-service problem with bonded doubler assemblies has been delamination caused by unstable surface preparation. Early fuselage skins with bonded doublers and inadequate surface preparation experienced severe delamination and subsequent corrosion. A majority of these delaminated doublers were the fail-safe tear straps (Fig. 27). Although the tear strap bond does not cany structural load, the bond...

Square-edge stiffened panels are used extensively on current production aircraft such as the 737,757 and 767, primarily in the aft fuselage (unpressurized section).

Plastics provides a means to producing monocoque constructions such as has been done in different applications that include toys to automotive body, motor truck, railroad car, aircraft fuselage and wings, and houses. Its construction is one in which the outer covering skin carries all or a major part of the stresses. The structure can integrate its body and chassis into a single structure. Unreinforced and RPs are used in these constructions (14, 34).
