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.
