Abstract

A process for the manufacture of an aircraft stowage container, comprising a bottom member A, a top member D, at least two side wall members B, C, and two plane end wall members 1. Said members are essentially rigid and plane. Additionally an essentially rigid closure flap member 3 may be provided. The process comprises the steps of preparing at least two layers of prepregs impregnated with a curable thermosettings for forming the top, bottom and side wall members or the U-shaped surround. Between at least two of said layers of prepregs 6 a honeycomb construction material 7 is interposed in a manner that several regions spaced apart from each other are defined by said honeycomb material thereby defining folding or bending regions. Then the layers of prepregs are bent or folded by applying them over a mould 5, and they are cured afterwards in an autoclave by beat application to a cured composite component 2. In this process mode the plane end wall members 1 are prepared separately and are connected with the cured composite component 2 to form the final stowage container. In another modification of the construction of the stowage container, in addition to the prepreg 6, separate prep…
