There is a need for a manufacturing method that achieves relatively high production rates with relatively low capital investment and operating costs, and/or is relatively flexible and relies on equipment that is less complicated than current advanced fiber placement (AFP) machines. Accordingly, there is provided a method of fabricating a composite structure comprises forming a plurality of modules each having an edge, each of the modules comprising a plurality of adjacently stacked uncured composite prepreg fibers, each of the plurality of modules being substantially planar; joining the plurality of modules together by joining respective edges of two adjacently positioned modules to form a scarf joint between the adjacently positioned modules, the respective edges are substantially co-planar, wherein an assembly is formed; after joining the plurality of modules to form the assembly, bending the assembly into a shape; and co-curing the assembly.
La présente invention concerne une structure composite à grande échelle fabriquée en formant une pluralité de modules en stratifié composite (208d, 208e) et en assemblant les modules le long de leurs bords (210) à l'aide de joints en biseau.
