Abstract This article studied the main problem of J type stiffened panels faced in the practical application, situation of
application for some important technology, for example, the precise fill cor-material of R area, outer mold forming process of
fillet, perpendicular positioning of frame-bolt type, assemble of co-cementing vacuum bag, have been introduced, and a deep
analysis has also been done for the technique related. The experiment results show that, the cor-material can be made precisely
with the precise calculation and the application for dedicated molds, by which, the quality of stiffened panels can be improved.
With the application of outer mold and frame-type location device, the surface quality, dimensional accuracy, positional accuracy
of J type stiffened panels will all be improved. Surface problem will induce with the use of vulcanized rubber for resist
strips and suitable soft mode. With the optimizing of auxiliary material laying method, risk of bridging and bag broken will reduce.
By the use of all these technique introduced below, we successfully made the stiffened panels that can be used, this part
can also be made bulkily.
