摘要： Method for manufacturing stiffened panels comprising the following steps: forming a first and a second wet skin, each comprising a plurality of plies of preimpregnated composite material; forming a plurality of pairs of wet stringers, comprising a plurality of plies of preimpregnated material, wherein forming each pair of wet stringers comprises a) forming an assembly having a central web extending between opposite end flanges, and b) cutting the assembly along a median plane so as to form a pair of wet stringers, placing the pairs of wet stringers on the first wet skin by means of removable supporting members; turning the second wet skin over and placing it on the pairs of stringers, so as to obtain a pair of wet panels arranged above each other; and subjecting the pair of wet panels to a same curing cycle.
